Question

How much energy (in joules) is released when 0.06 kilograms of mercury is condensed to a liquid at the same temperature?

Answer 1

The energy released when a certain amount of a substance condenses to a liquid is given by:

$Q=m \lambda_v$

where m is the mass of the substance and $\lambda_v$ is the latent heat of vaporization.

In this problem, the mass is m=0.06 kg, while the latent heat of vaporization of mercury is $\lambda_v=296 kJ/ kg$. Therefore, if we apply the formula we get:

$Q=(0.06 kg)(296 kJ/ kg)=17.76 kJ=17760 J$

So, the correct answer is

C. 17,705.1 J

Answer 2

The answer is ....  C. 17,705.1 J
