Inv. 4 Chemical Interactions I-check

Front

What is the effect of heating on the particles of a solid, such as steel?

Back

When a piece of solid steel is heated, the steel particles bump more often and move farther apart.

Front

What is the term for the process of reducing the volume of a sample of matter by cooling or reducing kinetic energy?

Back

Contraction.

Front

How does the appearance of a hot watermark compare to a room temperature mark?

Back

The hot watermark should not look the same as the room temperature mark; it is typically less pronounced.

Front

What happens to the space between particles when a substance is heated?

Back

The space between particles increases.

Front

True or False: The cold water mark should look different from the room temperature mark.

Back

True.

Front

What happens to the particles of soup when you warm it up in the microwave?

Back

The space between soup particles increases.

Front

What is the relationship between temperature and particle movement in solids?

Back

As temperature increases, particle movement increases.

Front

Define kinetic energy in the context of particle movement.

Back

Kinetic energy is the energy that particles possess due to their motion; higher temperatures result in higher kinetic energy.

Front

What is the difference between heating and melting a solid?

Back

Heating increases the kinetic energy of the particles without changing the state, while melting changes the solid into a liquid.

Front

What is thermal expansion?

Back

Thermal expansion is the increase in volume of a substance as its temperature increases.
