A closed, rigid tank fitted with a paddle wheel contains 2.2 kg of air, initially at 200oC, 1 bar. During an interval of 20 minutes, the paddle wheel transfers energy to the air at a rate of 1 kW. During this time interval, the air also receives energy by heat transfer at a rate of 0.5 kW. These are the only energy transfers. Assume the ideal gas model for the air, and no overall changes in kinetic or potential energy....

Five kg of oxygen (O​2​), initially at 430°C, fills a closed, rigid tank. Heat transfer from the oxygen occurs at the rate 425 W for 10 minutes. Assuming the ideal gas model with ​k ​ = 1.350 for the oxygen, determine its final temperature, in °C. Can't seem to find the right equations to use for this one, so I'm getting pretty stumped. Any help would be greatly appreciated

A closed, rigid tank is filled with water. Initially, the tank holds 0.6 lb of saturated vapor and 6.0 lb of saturated liquid, each at 212°F. The water is heated until the tank contains only saturated vapor. Kinetic and potential energy effects can be ignored. Determine the volume of the tank, in ft3, the temperature at the final state, in °F, and the heat transfer, in Btu.

A 500 L rigid tank contains a saturated water mixture at 200 C as shown: the mixture is 40% liquid and 60% vapour by volume (State 1). A valve on top of the tank is opened, and saturated vapor is slowly withdrawn from the tank. Heat transfer occurs during this process such that the temperature in the tank remains constant. The valve is closed when 50 % of the initial mass is withdrawn from the tank (State 2) (a) Determine...
