Multiple Choice

What is pressure?

• The amount of force exerted on a surface

• The surface area of an object

• The weight of an object

Multiple Choice

Gas pressure is caused by

• gas molecules colliding with surfaces
• gas molecules condensing to a liquid
• gas molecules hitting other gas molecule
• barometers

Multiple Choice

What is the instrument that measures air pressure called?

• Graduated cylinder
• Barometer
• Force scale
• Anemometer

Multiple Choice

A measure of how hot or cold something is; specifically a measure of the average kinetic energy of the particles in an object.

• Thermometer
• Temperature
• Absolute Zero
• Specific Heat

Multiple Choice

The temperature at which molecular energy is at a minimum (0 K on the Kelvin scale or -273.16 C on the Celsius scale).

• Specific Heat
• Plasma
• Absolute Zero
• Conduction

Multiple Choice

How does heat flow?

• block R to block S

• block S to block R

• heat does not flow between them

Multiple Select

Multiple Choice

What will happen to the volume of a gas if the pressure increases, with constant temperature ?

• Increase
• Decrease
• Nothing
• Explosion!

Multiple Choice

If you increase the pressure, what will happen to the temperature, if volume is constant?

• Increase
• Decrease
• Stay the same
• It will Blow Up

Multiple Choice

Increasing the temperature of a gas will _______ the pressure it exerts.

• increase

• decrease

• not affect

Multiple Select

Why does increasing the temperature of a gas increase the pressure it exerts? Select ALL that are correct.

• It increases the number of particles in the gas.

• It increases the speed of collisions between the particles and the container.

• It increases the size of the particles in the gas.

• It increases the number of collisions between the particles and the container.

Multiple Choice

If the temperature of a gas is kept constant but the volume is decreased, the pressure will _______.

• increase

• decrease

• remain constant

Multiple Choice

If the volume of a gas is kept constant but the temperature is decreased, the pressure will _______.

• increase

• decrease

• remain constant
