Question

How much heat will be required to increase the temperature of 1 kg of copper
from 25°C to 175°C if the specific heat of copper is 400 Joules/Kg°C:
(a) 60,000
(b) 60 J
(c) 6000J
(d) 600 J​

Answer 1

Answer:

Correct option is

C

38640 J

Given:

mass(m)=1kg

Heat energy required (Q)=?

Rise in temperature Δt=100−20=80

∘

C=80K

Specific heat capacity (c) 483Jkg

−1

K

−1

Specific heat capacity (c) =

Mass(m)×Riseintemperature

Heatenergy(Q)

483=Q/(1×80)

Q=38640J
