Front

What is a dependent variable in an experiment?

Back

The dependent variable is the factor that is measured or observed in an experiment, which changes in response to the independent variable.

In the context of energy transfer, what happens when higher-energy particles come into contact with lower-energy particles?

Back

Energy is transferred from the higher-energy particles to the lower-energy particles.

How do you calculate the average of a set of numbers?

Back

Add all the numbers together and then divide by the total count of the numbers.

Front

What happens to energy when a system is warming up?

What is matter?

Back

Matter is anything that has mass and takes up space, including solids, liquids, and gases.

Front

What is the independent variable in an experiment?

Back

The independent variable is the factor that is changed or controlled in an experiment to test its effects on the dependent variable.

Front

What is thermal energy?

Back

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

What is conduction?

Back

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

Front

What is convection?

Back

Convection is the transfer of thermal energy through the movement of fluids (liquids and gases) caused by differences in temperature.
