Front

What is energy conversion?

Back

Energy conversion is the process of changing energy from one form to another, such as electrical energy to thermal energy.

Front

What type of energy conversion occurs in a microwave oven?

Back

Electrical energy is converted into light and thermal energy.

Front

What type of energy is released by a kitchen mixer to the environment?

Back

Thermal energy is released to the environment during the energy conversion process.

Front

What phase change occurs when thermal energy is increasing and a substance is boiling?

Back

Boiling is the phase change that occurs when a substance transitions from liquid to gas due to increased thermal energy.

Front

What kind of energy do fossil fuels like gas, oil, and coal contain?

Back

Fossil fuels contain chemical energy, which can be released during combustion.

Front

What is an example of radiation?

Back

An example of radiation is a person getting a tan from the sun.

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter; it is the total kinetic energy of particles in a substance.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion, which depends on its mass and velocity.

Front

What is the difference between thermal energy and kinetic energy?

Back

Thermal energy is related to the temperature of a substance, while kinetic energy is the energy of motion of an object.

Front

What is the process of condensation?

Back

Condensation is the phase change where a gas turns into a liquid as it loses thermal energy.
