IPC: Methods of Heat Transfer & Q = m C ΔT

Front

What are the three types of heat transfer?

Back

Radiation, Conduction, Convection

Front

What is the formula to calculate heat energy (Q) transferred?

Back

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

Front

What is the specific heat of water?

Back

4.184 J/g°C

Front

What type of heat transfer occurs when boiling water on a stove?

Back

Convection

Front

What type of heat transfer occurs through direct contact of materials?

Back

Conduction

Front

What type of heat transfer occurs through electromagnetic waves?

Back

Radiation

Front

How much heat energy is transferred when 20.0 g of water changes temperature by 5°C?

Back

418 Joules

Front

What is the effect of increasing the mass of a substance on the heat energy required to change its temperature?

Back

Increasing the mass increases the heat energy required, as Q is directly proportional to m.

Front

What happens to the temperature of a substance when it absorbs heat?

Back

The temperature of the substance increases, assuming no phase change occurs.

Front

What is the role of specific heat in heat transfer?

Back

Specific heat determines how much heat energy is required to change the temperature of a substance.
