States of matter and thermal energy

Front

What makes a snowperson melt?

Back

Heat causing particles to speed up.

Front

When the temperature of matter decreases, what happens to the particles?

Back

The particles slow down and move closer together.

Front

What is temperature a measure of?

Back

A substance's average kinetic energy.

Front

Thermal energy is also known as ___________ energy.

Back

Heat.

Front

What happens to particles in an object at higher temperatures?

Back

Particles in an object move faster.

Front

Define 'states of matter'.

Back

The distinct forms that different phases of matter take on, typically solid, liquid, gas, and plasma.

Front

What is kinetic energy?

Back

The energy that an object possesses due to its motion.

Front

How does thermal energy relate to temperature?

Back

Thermal energy is the total energy of all the particles in a substance, while temperature measures the average kinetic energy of those particles.

Front

What happens to the particles in a solid when it is heated?

Back

The particles gain energy, vibrate faster, and may eventually change to a liquid.

Front

What is the difference between heat and temperature?

Back

Heat is the transfer of thermal energy, while temperature is a measure of the average kinetic energy of particles.
