A vertical piston–cylinder device contains water and is being heated on top of a range. During the process, 65 Btu of heat is transferred to the water, and heat losses from the side walls amount to 8 Btu. The piston rises as a result of evaporation, and 5 Btu of work is done by the vapor. Determine the change in the energy of the water for this process

ΔE =52 btu

Explanation:

givens:

E_h=65 btu

E_loss=8 btu

W_p=5 btu

solution:

the total change in the system energy can be calculated as follows,

ΔE=E_h-W_p-E_loss

 ΔE =52 btu

d would be the most obvious choice to this question. leaders are supposed to herd their underlings like a shepherd to sheep. a leader should also listen to others when they are talking to one other to gain a better understanding of their mission and surroundings.
