Question

the specific heat capacity of a metal is 160 J kg‐¹ K-¹ . Calculate the amount of heat energy required to raise the temperature of 1000 grams of the metal from 150°C to 415°C.​

Answer 1

Answer:

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
