The change from the condition where the object is water at 100oC to the condition where the object is vaopur at 100oC Since internal...

Case (1) = pressure is equal to atmospheric pressure Case (2) = pressure is higher than atmospheric pressure Pressure higher than...

I do not learn Clapeyron Clausius equation @kuruman what is the mistake in post #19?

I am not sure what you mean. ΔU = Q + W where W is work done on the system Q = m L where L is the specific latent heat of vaporization...

Increasing the pressure for same ΔV will increase the work done by the system so the work done on the system will decrease (will be more...

Because work done by the system = p . ΔV so higher p means higher W I wrote the formula as ΔU = Q + W so shouldn't the W there is work...

I think so. By taking ΔV to the same, we can say that the work done by the system will be higher. Let me try: For same ΔV, work done by...

ΔU = Q + W Q = ΔU - W I am not sure how to analyze the changes in ΔU and W. The value of p increases, but how do we know about ΔV? For...
