CI MIDDLE of Inv 4 - Kinetic Energy

Front

What is Kinetic Energy?

Back

Kinetic Energy is the energy that an object possesses due to its motion. It depends on the mass of the object and the speed at which it is moving.

Front

How does temperature affect the kinetic energy of particles?

Back

As temperature increases, the kinetic energy of particles increases, causing them to move faster.

Front

What happens to gas particles when they are compressed?

Back

When gas particles are compressed, they are forced closer together, increasing their density.

Front

What is the relationship between particle movement and temperature?

Back

Higher temperatures result in faster particle movement, while lower temperatures result in slower particle movement.

Front

What instrument is used to measure temperature?

Back

A thermometer is used to measure temperature.

Front

What occurs to a substance when its temperature decreases?

Back

When the temperature of a substance decreases, it typically contracts, meaning the particles come closer together.

Front

True or False: The number of particles in a gas changes when it is compressed or expanded.

Back

False. The number of particles remains the same; only their arrangement changes.

Front

What happens to the kinetic energy of particles when they become hotter?

Back

When particles become hotter, their kinetic energy increases, leading to faster movement.

Front

What is the effect of decreasing temperature on gas volume?

Back

Decreasing temperature generally causes the volume of a gas to decrease as the particles move closer together.

Front

Define 'contraction' in terms of particle arrangement.

Back

Contraction is the process where particles come closer together, often due to a decrease in temperature.
