Question

Mercury has one of the lowest specific heat capacities. If 257 J of heat are added to 0.45 KJ of mercury, the Mercury’s temperature will increase by 4.09 K. What is the specific heat capacity of mercury?

Answer 1

139.67 (J/kgk)

Step-by-step explanation:

Given data:

mass of mercury = m = 0.45 Kg

Amount of energy = Q = 257 J

Increase in the temperature = ΔT = 4.09 K

To find:

Specific heat capacity = C

Formula:

By using specific heat equation,

Q = m x C X ΔT

C = Q / m x ΔT

= 257J / o.45 kg x 4.09K

= 257J / 1.84

= 139.67 (J/kgk)

Specific heat of mercury is 139.67 (J/kgk).
