Temperature and Pressure

Front

What is temperature?

Back

Temperature is a measure of the average kinetic energy of the particles in an object. When temperature increases, the motion of these particles also increases.

Front

What happens to kinetic energy when molecules move faster?

Back

The faster the molecules move, the more kinetic energy they have, and the more spread out they become.

Front

What can change the state of matter?

Back

Changing the temperature or pressure can change the state of matter.

Front

How does pressure change underwater?

Back

The pressure under water increases with how deep you are.

Front

What is atmospheric pressure?

Back

Atmospheric pressure is the weight of the gas above an object on a given surface area. The higher the elevation, the lower the atmospheric pressure exerted because there is less air pressing down on the object.

Front

What is kinetic energy?

Back

Kinetic energy is the energy that an object possesses due to its motion.

Front

What is the relationship between temperature and particle motion?

Back

As temperature increases, the motion of particles increases.

Front

What is the effect of pressure on gas behavior?

Back

Increasing pressure on a gas can compress it, reducing its volume.

Front

What is the formula for calculating pressure?

Back

Pressure = Force / Area.

Front

What happens to gas pressure when temperature increases?

Back

When temperature increases, gas pressure also increases if the volume is held constant.
