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

Front

What is the formula to calculate heat transfer (Q) in a substance?

Back

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

Front

What is specific heat capacity?

Back

Specific heat capacity is the amount of heat required to raise the temperature of 1 gram of a substance by 1°C.

Front

What is the specific heat of aluminum?

Back

The specific heat of aluminum is 0.9025 J/g°C.

Front

How much heat is released when a 10.0 g piece of aluminum cools by 50.0°C?

Back

451 J.

Front

What is conduction in terms of heat transfer?

Back

Conduction is the transfer of heat energy through direct contact between materials.

Front

What are the three methods of heat transfer?

Back

The three methods of heat transfer are conduction, convection, and radiation.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases) caused by differences in temperature and density.

Front

What is radiation in the context of heat transfer?

Back

Radiation is the transfer of heat energy through electromagnetic waves, which can occur in a vacuum.

Front

What is a conductor?

Back

A conductor is a material that easily transfers heat, such as metals.

Front

What is an insulator?

Back

An insulator is a material that resists the transfer of heat, such as wood or plastic.
