Temperature and Kinetic Energy

Front

What is temperature?

Back

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

Front

What is kinetic energy?

Back

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

Front

How does temperature affect kinetic energy?

Back

As temperature increases, the kinetic energy of the particles in a substance also increases.

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of all the particles in a substance.

Front

How do you compare thermal energy in two substances at the same temperature?

Back

The substance with more mass will have more thermal energy, even if both are at the same temperature.

Front

What happens to particles in a substance when it is heated?

Back

The particles gain kinetic energy, move faster, and may spread apart, causing the substance to expand.

Front

What is the relationship between mass and thermal energy?

Back

Thermal energy is directly proportional to the mass of the substance at a constant temperature.

Front

What occurs when a solid is heated?

Back

The particles vibrate faster and may eventually overcome their fixed positions, leading to a change of state.

Front

What is the principle of thermal expansion?

Back

Thermal expansion is the tendency of matter to change in volume in response to a change in temperature.

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.
