Answer» 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
