1. Assuming pressure remains constant, calculate the final volume in each of the following cases:

a) A volume of 35.0 mL of gaseous hydrogen is heated from 20 °C to 120 °C;

b) A volume of 15 L of air is chilled from 80 °C to -25 °C.

2. The temperature of a room whose volume is 8.95 x 104 L goes from 20 °C to 30 °C. What volume of air will the room lose following this rise in temperature?

3. Calculate the initial volume of a sample of a gas if its final volume is 344 mL after being heated from -10 °C to 40 °C.
