    Undergrad Density and the ideal gas equation

    Could someone explain the connection between density, pressure, and temperature in relation to the ideal gas law to me? (For example what happened if the Temperature/pressure is kept konstant but the density changes with temeprature.) As I see it there are two ways to get the density into the...

    First law of thermodynamics applied to a submarine

    R(air)= cp-cv => cv=R(air)+cp...i accidentally wrote a minus sign but i meant plus -.-. What I can't really imagine though is what happens to the pressure during this process?

    First law of thermodynamics applied to a submarine

    First law of thermodynamics Hallo, i hope someone can help me with the following question: A submarine contaiins 1000m^3 of air and has a temperature and pressure of 15°C and 0.1MPa respectively. Due to the cold seawater a heatflow of 60 MJ/h occurs. The machines on the otherhand add...
