Question : Air undergoes isentropic compression from the initial temperature and pressure T1 = 25°C and P1 = 100 kPa to the final pressure P2 = 500 kPa. Find the final temperature T2 (in Celsius). Justify your answer and show your work

An automobile tire is inflated with air originally at 10.0°C and normal atmospheric pressure. During the process, the air is compressed to 32.0% of its original volume and the temperature is increased to 34.0°C. (a) What is the tire pressure? Pa (b) After the car is driven at high speed, the tire's air temperature rises to 85.0°C and the tire's interior volume increases by 2.00%. What is the new tire pressure (absolute)? Pa Need Help?

You have 2 kg of saturated steam at P = 2 MPa. How much heat do you have to add to raise the temperature to 600degC if the pressure stays isobaric at 2000 kPa?
