What is thermal energy?

Back

Thermal energy is the total kinetic energy of the particles in a substance. It is related to temperature and the amount of substance.

What happens to the temperature of an object when it gains thermal energy?

Back

When an object gains thermal energy, its temperature increases as the kinetic energy of its molecules increases.

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion. It depends on the mass and speed of the object.

How does the size of an object affect its thermal energy?

Back

Larger objects generally have more thermal energy because they contain more particles, even if they are at the same temperature as smaller objects.

What is the relationship between temperature and kinetic energy?

Back

Temperature is a measure of the average kinetic energy of the particles in a substance. Higher temperature means higher average kinetic energy.

What occurs during heat transfer?

Back

Heat transfer occurs when thermal energy moves from a hotter object to a cooler one until thermal equilibrium is reached.

What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two objects in contact no longer transfer heat to each other, meaning they are at the same temperature.

Front

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

Back

When a substance is heated, its molecules move faster and spread apart, increasing the substance's thermal energy.

What is the formula for calculating kinetic energy?

Back

The formula for kinetic energy (KE) is KE = 1/2 mv², where m is mass and v is velocity.

What is the effect of dropping a hot object onto a cool surface?

Back

When a hot object is dropped onto a cool surface, thermal energy transfers from the hot object to the cool surface, increasing the surface's temperature.
