When 5 g of water is boiled at 100 C and 100 kPa pressure, 8355 cm3 of steam is
formed. The specific latent heat of vaporisation of water is 2.26 MJ kg-1. The questions below require you to give the numerical value as well as sign of certain physical quantities.
(i) How much work is done by the expanding water vapour?
(ii) What heat energy is absorbed by the water while it boils?
(iii) What is the increase in the internal energy of the water molecules?
Sorry, I want the answer, not the translation. Thank you!
