Question

A sample of mercury has a mass of 500 g when it absorbs 200 joules the temperature is found to have increased from 25°C to 29°C Celsius what is the specific heat of mercury

Answer 1

The specific heat of mercury can be calculated using the formula:

q = m × c × ΔT

where q is the heat absorbed, m is the mass of the mercury, ΔT is the change in temperature, and c is the specific heat of mercury.

In this case, q = 200 J, m = 500 g, ΔT = 29°C - 25°C = 4°C, and c is unknown. Substituting these values into the formula, we get:

200 J = 500 g × c × 4°C

Simplifying, we get:

c = 200 J / (500 g × 4°C)

c = 0.1 J/g°C

Therefore, the specific heat of mercury is 0.1 J/g°C.
