Thermal Energy and Kinetic Theory

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of all the particles in a substance, which is related to its temperature.

Front

How does temperature relate to particle movement?

Back

Higher temperatures indicate that particles are moving more quickly, while lower temperatures indicate slower particle movement.

Front

What is the difference between heat and temperature?

Back

Heat is the transfer of thermal energy from one object to another, while temperature is a measure of the average kinetic energy of the particles in a substance.

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases) caused by differences in temperature and density.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as infrared radiation.

Front

What happens when ice is added to hot soup?

Back

Heat flows from the hot soup to the ice, causing the soup to cool down and the ice to melt.

Front

Why does warm air rise?

Back

Warm air is less dense than cool air, so it rises as cooler, denser air sinks.

Front

What is the principle of thermal equilibrium?

Back

Thermal equilibrium occurs when two objects at different temperatures come into contact and heat flows between them until they reach the same temperature.

Front

What is specific heat capacity?

Back

Specific heat capacity is the amount of heat required to raise the temperature of one gram of a substance by one degree Celsius.
