Back

They would speed up.

Front

How do you calculate the mass of a substance given heat energy, specific heat, and temperature change?

Back

Use the formula: mass = heat energy / (specific heat × temperature change).

Front

What is the formula for calculating heat energy?

Back

Heat energy (Q) = mass (m) × specific heat (c) × temperature change (ΔT).

Front

What is the unit of specific heat?

Back

Joules per kilogram per degree Celsius (J/KgºC).

Front

What is thermal energy?

Back

The total energy of all the particles in a substance.
