Consider a stoichiometric mixture of H2 and O2 at standard condition (298.15 K and 1.05 x 105 Pa,) at the upstream. The specific heat ratio of the mixture is 1.4. The heat of combustion for this stoichiometric mixture g. is 190.5 kJ/mole. The universal gas constant R =8. 314 J/mole/ K. (1) calculate the average molecular weight of the mixture MW, the local sound speed au, the density pu (2) if the upstream flow velocity u-1 m/s, plot the Rayleigh lines, and the Hugoniot hyperboles with its asymptotes. (3) if the upstream flow velocity u= 2000 m/s, what is the downstream detonation pressure po, and density Po

The temperature at state A is 20.0ºC, that is 293 K. During the last test, you have found the temperature at state D is 73.0 K and n = 164 moles for this monatomic ideal gas. What is the change in thermal energy for process D to B, in MJ (MegaJoules)?

An insulated container contains two moles of an ideal gas at atmospheric pressure. Keeping the pressure constant, if the temperature of the gas is increased by 50 °C, then its volume increases by 400 cm3 and if the temperature is increased by 100 °C, then its volume increases by 600 cm³. Determine the initial volume and temperature of the gas. (Write the equation of ideal gas initially, after the temperature increase of 50 °C, and after increase of temperature by 100 °C. Combine these three equations to find the initial volume and temperature)

A good explanation would be really helpful
