Study Notes
Gas Laws and Temperature Changes
- The temperature of a gas sample at a constant pressure is increased from 5°C to 10°C. A small increase in volume is expected.
Balloon Volume and Pressure Changes
- At a pressure of 1.0 atm, the volume of a balloon is 2.7 L. Assuming that the temperature remains constant, what will the volume of the balloon be if the pressure is increased to 1.4 atm?
- The volume will decrease.
Balloon Volume, Pressure, and Temperature
- A 3.0 L balloon at 1.1 atm and 310 K floats upward in the atmosphere. What is the volume of the balloon when the pressure is 0.95 atm and the temperature is 290 K?
- The volume will increase.
