Front

What is the formula for calculating heat transfer (Q) in relation to mass, specific heat, and temperature change?

Back

Q = m C ΔT

What does 'C' represent in the formula Q = m C ΔT?

Back

Specific heat capacity

Front

What is the unit of specific heat capacity?

Back

J/(g·°C) or J/(kg·K)

Front

What is the difference between conduction and convection?

Back

Conduction is heat transfer through direct contact, while convection is heat transfer through fluid movement.
