A rigid insulated tank is separated into two rooms by a stiff plate. Room A of 0.5 m3 contains air at 250 Kpa, 300 K and room B is 1 m3 has air at 200 Kpa, 1000 K. the plate is removed and the air comes to a uniform state without any heat transferred. find the final temp and pressure of the room.An ideal gas is 45 psig and 800F is heated in a closed container to 130 0F. What is the final pressure?An air bubble rises from the bottom of a well where the temperature is 25 0C, to the surface where the temperature is 27 0C. Find the percent increase in the volume of the bubble if the depth of the well is 5m. Atmospheric pressure is 101.528 kPaa.A 3000 cm3 tank initially contains compressed air at 600 kPag and 28 oC. Determine the mass of air to be withdrawn from the tank to reduce its pressure to 80 kPag while the temperature remains unchanged.

A rigid insulated tank is separated into two rooms by a stiff plate. Room A of 0.5 m3 contains air at 250 Kpa, 300 K and room B is 1 m3 has air at 200 Kpa, 1000 K. the plate is removed and the air comes to a uniform state without any heat transferred. find the final temp and pressure of the room.
An ideal gas is 45 psig and 800F is heated in a closed container to 130 0F. What is the final pressure?
An air bubble rises from the bottom of a well where the temperature is 25 0C, to the surface where the temperature is 27 0C. Find the percent increase in the volume of the bubble if the depth of the well is 5m. Atmospheric pressure is 101.528 kPaa.
A 3000 cm3 tank initially contains compressed air at 600 kPag and 28 oC. Determine the mass of air to be withdrawn from the tank to reduce its pressure to 80 kPag while the temperature remains unchanged.
