Water is heated in an open pan where the air pressure is 105Pa10^5\,\text{Pa}. The water remains a liquid, which expands by a small amount as it is heated. Determine the ratio of the heat absorbed by the water to the work done by the water. (γ\gamma for water =103/°C= 10^{-3}/\degree\text{C}, S=1cal/g°CS = 1\,\text{cal/g}\degree\text{C})
