![The density of water at 20∘C and 1 atm pressure is p1 = 998 kg m3. The coefficient of volume expansion at the average temperature of 35∘C is β = 0.337×10−3. The isothermal compressibility of water is given to be α = 4.8×10−5. Consider water initially at 20∘C and 1 atm. Determine the final density of the water with the condition of: a) if it is heated to 50∘C at a constant pressure of 1 atm [20 marks] b) if it is compressed to 100 -atm pressure at a constant temperature of 20∘C. Take the isothermal compressibility of water to be α = 4.8×10−5 atm. [20 marks] (Assumption: The coefficient of volume expansion and the isothermal compressibility of water are constant in the given temperature range. An approximate analysis is performed by replacing differential changes in quantities by finite changes.) [TOTAL: 40 marks]](https://www.doubtrix.com/uploads/editor/9399766226YDxPEllnmA.png)
