Someday, Sublimate

Topic: States of matter – solids, liquids, & gases (middle/high school chemistry)

by Lodge

Someday, sublimate I am matter with shape and volume They call me solid, ‘cause my particles are fixed and arranged More amorphous ‘cause my melting point depends on my pattern I do the rubber plastic butter change Should I be melting from a solid to a liquid? Take in energy, my particles they move real fast Or should I freeze...so particles can chill and move slowly Here’s an ice-covered photograph Chorus: Someday, I hope to sublimate Move from a solid to gas without the liquid state And that way, I’ll never evaporate ‘Cause I’m already a fluid without a volume or – shape With particles so hard to contain Viscous, liquid take the shape of this container You’re free to move you’re like a fluid so flow flow flow With a high resistance, like honey, you’re acting like a winner Surface tension so high I know Go from a liquid to a gas, you get vaporized It’s endothermic, when the particles gain top speed Evaporate on the surface – the reverse or otherwise Condensation is all we need I want to change position and distance so easily And do it speedily I want to fit into containers like an air-born fluid That’s so good I want my particles to spread out and fill the space available It’s so attainable...so I should!

Someday, Sublimate I am matter with shape and volume They call me solid, ‘cause my particles are fixed and arranged Define solid: ________Matter that has a definite shape and definite volume_______ More amorphous ‘cause my melting point depends on my pattern What are the two types of solids? __amorphous___________ and ___________crystalline____ Define melting point. _______Specific temperature at which a solid melts______________ Characteristics of ____amorphous_______________ solids: -______particles are not arranged in a regular pattern___________ -________No distinct melting point__________________________________ Characteristics of ___crystalline________________ solids: -___________Particles are arranged in a regular pattern_____________ -____________Specific melting point______________________________ I do the rubber plastic butter change These are 3 examples of amorphous solids. Give one more: _______humans____________ Give 3 examples of crystalline solids. _______Salt____________ ____sugar__________ ______Quartz___ Should I be melting from a solid to a liquid? Define Melting: ____change in state from a solid to a liquid__________________________ __________________________________________________________________ Take in energy, my particles they move real fast

Explain what happens to the energy and particles when this physical change in matter occurs: __________energy is absorbed which makes particles vibrate and move so

_____fast that they break free from their fixed positions________________________ Or should I freeze…so particles can chill and move slowly Define freezing: ______change from a liquid to a solid_______________________________ ___________________________________________________________________________________ Explain what happens to the energy and particles when a liquid freezes: _________________________ _______energy is released and the particles slow down until they form regular patterns Here’s an ice-covered photograph How could taking a photograph be compared to the process of freezing? Particles slow down and form a static object. A photograph is capturing an event and creating a static representation of that event. Someday, I hope to sublimate Define sublimation: ___change in state from solid to gas with entering the liquid state Move from a solid to gas without the liquid state Would you like to sublimate? Why or why not? And that way, I’ll never evaporate Evaporation is ____vaporization that takes place only on the surface of the liquid ‘Cause I’m already a fluid without a volume or – shape Define gas: ______state of matter with no definite shape or volume_______________ Gas and liquid are both considered to be fluids because ______particles are free to move_______ ____________________________________________________________________________________ How does breathing demonstrate that gasses are fluids? While breathing, gasses in the air flow freely through the body and back out again taking on different shapes in each part of your body. With particles so hard to contain Why are particles of gas so hard to contain? Because they are free to move

Viscous, liquid take the shape of this container Define viscosity: ___a liquids resistance to flow_____________________________________ Define liquid: ______state of matter in which particles are free to move, have a definite volume, no definite shape You’re free to move you’re like a fluid so flow flow flow

Explain why the shapes of the liquids in these 16oz bottles are different Because particles are free to move in a liquid, there is no definite shape…so it takes on the shape of its container. With a high resistance, like honey, you’re acting like a winner

Does honey have a higher or lower viscosity than Gatorade or Coke? Why? ____Higher viscosity. The particles in honey are attracted to __each other more strongly in honey than in Gatorade or Coke_____ Surface tension so high I know Define surface tension: _____The strength of attraction of the particles ________ __on the surface of a liquid___________________________________________________ Would honey have a higher or lower surface tension than Gatorade or Coke? Why? __Higher. There is more attraction to particles of honey on the surface than Gatorade or _____Coke__________________________________________________________________________ Go from a liquid to a gas, you get vaporized Define vaporization: ____change in state from a liquid to a gas_______________________ The two main types of vaporization are ____Evaporation______ and ___Boiling___________ It’s endothermic, when the particles gain top speed

What happens to the particles when a liquid boils?

They absorb energy which makes them move fast and they eventually become a gas Why is that considered to be an endothermic reaction? Energy is absorbed to make the particles move faster Evaporate on the surface – the reverse or otherwise What is the difference between evaporation, boiling and vaporization? Evaporation - vaporization on the surface of a liquid Boiling - vaporization throughout the liquid…on the surface and below the surface Vaporization - when the entire liquid becomes a gas at the same time When would immediate vaporization be possible? If a meteor was to hit the earth Condensation is all we need What is condensation? ____change in state from a gas to a liquid_______________________ ___________________________________________________________________________________ How is condensation the reverse or opposite of evaporation? Condensation is the change from gas to liquid…evaporation is the change from a liquid to a gas. I want to change position and distance so easily And do it speedily Only a __gas___________ has the ability to change position and distance easily and quickly. I want to fit into containers like an air-born fluid That’s so good What would happen to the gas particles if the lid of the container was removed? Particles would escape and fill the space made available to them. Why? Because gas particles have no definite shape or volume and are free to move. I want my particles to spread out and fill the space available It’s so attainable…so I should! Would you rather be a liquid or a gas? Why? ____________________________________________________________________________________ ____________________________________________________________________________________
