Question

How many Joules are required to raise the temperature of 4.66 g of CCl4 from 20.9◦C to 76.8◦C?

The specific heat capacity of CCl4 is 0.856 J/g◦C.

Answer 1

Heat required to raise temperature : 224.02 J

Further explanation

Given

mass CCl4 = 4.66 g

Δt= 76.8 - 20.9 =55.9 °C

c = The specific heat capacity of CCl4 = 0.856 J/g◦C.

Required

Heat /energy required

Solution

Heat can be formulated

Q=m.c.Δt

`\tt Q=4.66* 0.86* 55.9\\\\Q=224.02~J`
