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 propane tank with 75 gallons of liquid propane is at 50 F in a sealed tank. The tank develops a significant leak and propane escapes and vaporizes in a short period of time. To solve this problem you must use the propane tables not the common liquid properties. What is the temperature near the hole in the propane tank due to the escaping propane in Fahrenheit to three significant digits? .   Include a minus sign if appropriate. How many...

A mass of m=1kg of steam is contained in a closed rigid container. Initially the pressure and temperature of the steam are: p1= 1.5 MPa and t1=240?C, respectively. Then the temperature drops to T2 =100?C as the result of heat transfer to the surroundings. Determine: a) quality of the steam at the end of the process, b) percentage of volume that is occupied by the saturated liquid at the final state, c) heat transfer with the surroundings per unit mass...
