Heat and Thermal Energy

Front

What is the formula to calculate the energy transferred when raising the temperature of a substance?

Back

Energy (Q) = mass (m) × specific heat (c) × change in temperature (ΔT)

What is convection in the context of thermal energy transfer?

Back

Convection is the transfer of thermal energy when particles of a fluid move from one place to another.

What does a lower specific heat indicate about a material's temperature change when energy is absorbed?

Back

The lower a material's specific heat, the more its temperature rises when a given amount of energy is absorbed by a given mass.

What is thermal energy?

Back

Thermal energy is the total kinetic energy of the particles in a substance.

Front

What is the difference between conduction, convection, and radiation?

Back

Conduction is heat transfer through direct contact, convection is heat transfer through fluid movement, and radiation is heat transfer through electromagnetic waves.
