According to the ideal gas law, decreasing the volume of a closed reaction container increases the thermal energy because the

• pressure and collision frequency increase.

• collision frequency decreases.

• temperature remains the same.

• R is multiplied.

How is the pressure of a gas related to its concentration of particles?

• Pressure will expand a gas, enlarging its volume and reducing its density and concentration of particles.

• Pressure will magnify a gas, developing its volume and multiplying its density and concentration of particles.

• Pressure will compress a gas, reducing its volume and giving it a greater density and concentration of particles.

• Pressure will accelerate a gas, extending its volume and allowing a smaller density and concentration of particles.

Under which set of circumstances will the pressure of a gas DEFINITELY increase?

• Increasing the moles and increasing the volume of the gas.

• Raising the temperature and reducing the volume of the gas.

• Lowering the temperature and reducing the volume of the gas.

• Raising the temperature and increasing the volume of the gas.

If you fill up a balloon with a small amount of air, then set it in direct sunlight, you will see that the balloon expands. This expansion is due to an increase in volume, which results from

• a decrease in the pressure of the air in the balloon.

• an increase in the temperature of the air in the balloon.

• an decrease in the pressure of the air outside of balloon.

• an increase in the temperature of the rubber that makes the balloon.
