Question

calculate the amount of heat energy required to change the temperature of an iron ball of mass 3 kg from 30 °C to 200°C ( specific heat capacity of an iron ball is 460 J Kg.k pls fast ​

Answer 1

Answer:

This is an example and formula do it like this

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
