FLASHCARDIZZ Energy and Phases of Matter Test Review

Front

What is an endothermic process?

Back

An endothermic process is a reaction or change that absorbs heat from the surroundings.

Front

What is an exothermic process?

Back

An exothermic process is a reaction or change that releases heat to the surroundings.

Front

What is the specific heat formula?

Back

The specific heat formula is Q = mcΔT, where Q is heat energy, m is mass, c is specific heat, and ΔT is the change in temperature.

Front

What does the Kinetic Molecular Theory state about molecules?

Back

The Kinetic Molecular Theory states that molecules are always in motion.

Front

How do liquids and gases behave in terms of shape?

Back

Liquids and gases both take the shape of their container.

Front

What is the law of conservation of matter and energy?

Back

The law of conservation of matter and energy states that matter and energy cannot be created or destroyed, but can only be transformed from one form to another.

Front

What is the specific heat of iron?

Back

The specific heat of iron is 0.10 J/g°C.

Front

How do you calculate the mass of a substance using heat energy?

Back

To calculate mass, rearrange the specific heat formula: m = Q / (cΔT).

Front

What happens to matter when it absorbs thermal energy?

Back

When matter absorbs thermal energy, it may change phase, such as from solid to liquid.

Front

What is the relationship between temperature and kinetic energy?

Back

As temperature increases, the kinetic energy of molecules also increases.
