Answer to Question #90472 in Physics for Alex

Question

1. One mole of a diatomic ideal gas is cooled from 200oC to 50oC. Determine the change in the translational kinetic energy and the change in the internal energy of the gas.
2. Calculate the change in entropy when 12g of water at -10oC is raised to 100oC and convert to steam at 100oC. Assume that specific heat of water cwater = 4190 J·g-1·K-1, heat of vaporization Lv = 2256 kJ/kg,specific heat of ice cice = 2220 J·g-1·K-1, heat of fusion LF = 334 kJ/kg
3. Two moles of a monatomic ideal gas (ɣ = 1.67) initially at pressure P1, volume V1, temperature T1 undergoes isobaric process to volume V2 = 2V1. The gas is expanded adiabatically to V3 =3V1. Determinefinal temperature of gas T3 if T1 = 298 K, and sketch the diagram for these 2 processes.
4. One mole of an ideal gas is first compressed isothermally at 380 K to half of its initial volume. Then 450 J of heat is added to it at constant volume. So, what are the network and total change in internal energy after 2 processes?
