Two process are shown that take an ideal gas from state 1 to state 3. Compare the work done by process A to the work done by process B.

1. WA = WB = 02. WA > WB

3. WA = WB but neither is zero4. WA < WB

Which of the following processes involve heat?

1. The brakes in your car get hot when you stop.2. A steel block is placed under a candle.3. You push a rigid cylinder of gas across a frictionless

surface.4. You push a piston into a cylinder of gas, increasing

the temperature of the gas.5. You place a cylinder of gas in hot water. The gas

expands, causing a piston to rise and lift a weight. The temperature of the gas does not change.

Objects A and B are brought into close thermal contact with each other, but they are well isolated from their surroundings. Initially TA = 0°C and TB = 100°C. The specific heat of A is more than the specific heat of B. The two objects will soon reach a common final temperature Tf. The final temperature is

1. Tf > 50°C.

2. Tf = 50°C.

3. Tf < 50°C.
