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

Front

What is the formula to calculate heat transfer?

Back

Q = m C ΔT, where Q is the heat energy, 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 degree Celsius.

Front

How do you calculate the heat energy required to change the temperature of a substance?

Back

Heat energy (Q) can be calculated using the formula Q = m C ΔT.

Front

What is conduction in the context of heat transfer?

Back

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

Front

What is the specific heat of aluminum?

Back

The specific heat of aluminum is 0.903 J/g°C.

Front

If a substance has a high specific heat capacity, what does that imply about its temperature change?

Back

A high specific heat capacity means that the substance requires more heat energy to change its temperature.

Front

What happens to the speed of molecules when energy increases?

Back

The speed of molecules increases when energy increases.

Front

What is the relationship between mass, specific heat, and heat energy?

Back

The relationship is given by the formula Q = m C ΔT, indicating that heat energy is directly proportional to mass and specific heat.

Front

What is the heat transfer process when walking barefoot on hot asphalt?

Back

The heat transfer process is conduction.

Front

How do you determine the mass of a substance if you know the heat energy, specific heat, and temperature change?

Back

You can rearrange the formula Q = m C ΔT to find mass: m = Q / (C ΔT).
