Explanation

To find the increase in internal energy, we can use the equation:

ΔU = Q - W

where ΔU is the change in internal energy, Q is the heat energy added (which is the latent heat of vaporization in this case), and W is the work done.

Given:

Q = 2240 J (latent heat of vaporization of water per gram)

W = 168 J (work done in the process of vaporization)

Now, we can plug in the values:

ΔU = Q - W

= 2240 J - 168 J

= 2072 J

Explanation

Explanation

A gas being cooled is a system where entropy is decreasing. 

When a gas is cooled, its molecules slow down and become more ordered, leading to a decrease in entropy. 

Explanation

During the isothermal process, the temperature remains constant throughout the process.

In an isothermal process, the temperature of the system stays constant while pressure and volume may change.
