a). You have a 50 L steel tank full with gasoline at -20 0C. What is going to be the volume difference for both tank and fuel at 40 0C? Is the fuel going to fit in the fuel tank? b). Consider there is a problem with the temperature controlling and temperature dropped to -30 0C. Suddenly. What is going to be the volume difference when comparing with gasoline at -20 0C.

es 20. How many Btu need to be added to change 5 lb of ice at 30°F to steam at 215°F? Refer to tables for latent heat values as needed for calculations.

A rigid container, perfectly insulated against heat, is divided into two compartments by a curtain. One of the chambers contains 0.1 m3 of nitrogen at a temperature of 50°C and a pressure of 200 kPa. In the other compartment, there is oxygen in a volume of 0.2 m3 at a temperature of 100°C and a pressure of 300 kPa. By removing the curtain in between, the gases are mixed. Assuming constant specific heats,a) Find the final temperature and pressure of the mixture.b) Find the molar mass and partial pressures of the mixture gas.c) By removing the insulation around the rigid container, the gas mixture is heated up to 150°C. Find the final pressure, temperature change and total entropy change (T=25°C).

Q. A chamber filled with ideal gas expands from V to 2V. How much is the entropy change assuming that the process isa) isobar (reversible),b) isotherm (reversible),c) adiabatic (reversible),d) free expansion (irreversible)
