A balloon originally had a volume of 4.39 L at 44°C and a pressure of 729 mmHg. To what temperature must the balloon be cooled to in order to reduce its volume to 3.78 L at constant pressure?
A balloon is filled with 30. L of helium gas at 1.0 atm. What is the volume of the balloon when it rises to an altitude where the air pressure is only 0.25 atm?
the volume does not change
A 250. cm3 sample of neon is collected at standard temperature and pressure. Assuming the volume remains constant, what would be the pressure of the neon at 44.0°C?
The pressure on a gas at -18.0°C is changed from 101.3 kPa to 40.5 kPa. What will be the new temperature of the gas if the volume remains the same?
Which of the following statements about the Combined Gas Law is TRUE?
The mass of gases must be included in all calculations.
Volumes must be calculated in Liters.
Temperatures must be calculated in Kelvins.
Pressures must be calculated in atmospheres.
A gas inside a sealed metal container is heated, causing the internal gas pressure to increase. Which of the following statements best describes why this happens?
The gas particles increase in velocity and hit the sides of the container more often.
The volume of the container decreases slightly, causing the gas particles to hit the sides of the container more often.
The gas particles increase in mass and hit the sides of the container with greater force.
The number of moles of gas inside the container increases, resulting in more collisions.
Which of the following is NOT a part of the Kinetic Theory?
Gas particles move in straight paths.
Gas particles are very tiny.
Gas particles are very close together.
Gas particles bounce off each other.
Which gas law corresponds most closely to this graph?
Combined Gas Law
A sample of gas at 1.0°C is expanded at constant pressure from 10. L to 15 L. The final temperature is:
A sample of gas initially at 4.00 atm was compressed from 8.00 L to 2.00 L at constant temperature. After the compression, the gas pressure was:
