What is ideal gas equations?

At E °C, 30mL of coffee is forgotten in a thermos glass. If fresh coffee at F °C is added to the cooled coffee, the temperature of the coffee rises to G °C under room conditions. Calculate the amount of coffee added to the thermos. A two-digit number ending in 0 or 5, where E < G < F)

Steam enters a turbine from a height of 6 m, at 50m/s speed at 2MPa pressure and 350°C, and after 8.5kW heat loss to the environment, it exits the turbine at 0.1Mpa pressure, with a dryness degree of 0.92, from a height of A meter at a speed of 200m/s. (A indicates a single number height)

Calculate the power of the turbine if the mass of steam entering the turbine is 1.5kg/s.

10 kg of air is contained in a constant volume container at a temperature of AA°C and a pressure of 150kPa. How much air is pressed into the container, its pressure is 250kPa and its temperature is BB°C? (AA and BB are a two-digit number ending in 0 or 5)

Using Rayleigh-Jeans formula, find the total energy density. Can you explain Stefan-Boltzmann

law from this? Explain your answer.

We have equal amounts of two identical ideal gases at the same temperature T but at different

pressures p1 and p2 in two containers. Containers are connected. Find the change in entropy.

Find the number of oxygen molecules in 0.1 kg, whose speeds lie between 195 and 205 m/s at

0C.
