Heat and Temperature

Front

What happens to the average kinetic energy of particles as the temperature of a substance rises?

Back

The average kinetic energy of the particles increases.

Front

What is the term for the movement of thermal energy from a warmer object to a cooler object?

Back

Heat.

Front

In which state of matter do particles move faster, gas or solid?

Back

Particles move faster in a gas.

Front

When making iced tea, which direction does thermal energy flow when ice is added to hot tea?

Back

Thermal energy flows from the tea to the ice.

Front

In which state of matter are particles moving the fastest and are far apart?

Back

Gas.

Front

What is temperature a measure of?

Back

Temperature is a measure of the average kinetic energy of the particles in a substance.

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.

Front

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

Back

The particles vibrate faster and may eventually break free from their fixed positions.

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two objects in contact do not exchange thermal energy because they are at the same temperature.

Front

What is conduction?

Back

Conduction is the transfer of thermal energy through direct contact between materials.
