Question

how many heat is required to raise the temperature of 5 gram of Mercury from 20 degree Celsius to 200 degree Celsius??
( specific heat capacity of mercury= 0.138 x 10 ^3 j/kg degree C)

Answer 2

hey dear here is ur answer
The formula for specific heat is:

E=mcθ, where:

E is the energy needed in joules,

m is the mass in kilograms,

c is the specific heat,

θ is the change in temperature, Celsius of Kelvin doesn't matter.

Here,

m=0.125kg

c=480J/kg∘C

θ=5∘C, and inputting:

E=0.125⋅480⋅5

E=300J of energy is needed.
