Answer:

B. 17,705.1 J

Explanation:

The hear released when the mercury condenses into a liquid is given by:

Q=m \lambda_v

where

m = 0.06 kg is the mass of the mercury

\lambda_v is the latent heat of vaporization

For mercury, the latent heat of vaporization is \lambda_v = 296 kJ/kg, so the heat released during the process is:

Q=(0.06 kg)(296 kJ/kg)=17.76 kJ = 17,760 J

So, the closest option is

B. 17,705.1 J

The energy ( in joules ) released when 0.06 kilograms of mercury is condensed to a liquid at the same temperature is about 697.08 J. in other to solve this problem, should know the latent heat of fusion of mercury which is equal to about 11.4 kJ/kg and multiplying by mass of mercury.
