Heat transfer = (mass)(specific heat)(temperature change)

Q = mcΔT

Q = heat content in Joules

m = mass

c = specific heat, J/g °C

T = temperature

ΔT = change in temperature

Heat Transfer Formula Questions:

1) How much energy is transferred if a block of copper with a mass of 50 g is heated from 20°C to 100 °C? The specific heat of copper, Cu, is c = 0.386 J/g°C.

Answer: The temperature change Δ T = 100 °C - 20 °C = 80 °C. The mass, m = 50 g. Use the formula for Heat Transfer.

Q = mcΔT

Q = (50 g)(0.386 J/g°C)(80 J/g°C)

Q = 1544 Joules


I hope this will help you
