It takes 11.2 kJ of energy to raise the temperature of 145 g of benzene from 23.0°C to 68.0°C.What is the specific heat of benzene?

Question

Quizplus · Accepted Answer

The formula to calculate the heat energy required to raise the temperature of a substance is given by:

q = m × c × ΔT

where q is the heat energy required, m is the mass of the substance, c is the specific heat of the substance, and ΔT is the change in temperature.

Plugging in the given values, we get:

11.2 kJ = 145 g × c × (68.0°C - 23.0°C)

Solving for c, we get:

c = 72 J/(g ∙ °C)

Therefore, the specific heat of benzene is 72 J/(g ∙ °C).
