Overall Review G9 Electricity

Front

What is evaporation?

Back

Evaporation is the process where liquid turns into gas.

Front

What is the formula to calculate heat energy required to change temperature?

Back

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

Front

What is the specific heat of copper?

Back

The specific heat of copper is 0.385 J/(g∙°C).

Front

How do you calculate density?

Back

Density = mass/volume.

Front

What is the density of an object with a mass of 4g and a volume of 2cm³?

Back

Density = 4g / 2cm³ = 2 g/cm³.

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 fluids (liquids and gases) due to the movement of the fluid itself.

Front

What is required for convection to occur?

Back

Fluids are required for convection to happen.

Front

What is the process of heat transfer through empty space called?

Back

Radiation.

Front

What happens to water when it evaporates?

Back

Water changes from a liquid state to a gaseous state.
