One mole of water evaporates in an open container at 273 Kelvin. The formula is H20 liquid---->>>>H20 gas. What is the work done on or by the system?
a. 2.3 kJ
b. -2.3 kJ
d - 22kJ
Answer: b. -2.3 kJ
The system is the water in the container.
Here water is expanding against constant atmospheric pressure (1 atmosphere) to become gas. Hence work is done by the ...
The solution calculates work done when one mole of water evaporates in an open container at 273 Kelvin.
