Question

Find the specific heat capacity of a 40 g sample of iron whose temperature is increased by 10°C when 2000 J of energy is being supplied.

Answer 1

Given:

Q = 2000 J, m = 40 g, ΔT = 10°C

Using Q = mcΔT

c = `Q/(mΔT)`

= `2000/(40 xx 10)`

= 5 J/g°C

The specific heat capacity of iron is 5 J/g°C.
