mol K 1) The Ideal Gas Law, PV = RT, relates the pressure (P, in pascals), temperature (T, in Kelvin), and volume (V, in cubic meters) of 1 mole of a gas (with R = 8.314 as the universal gas constant), and describes the behavior of gases that do not liquefy easily, such as oxygen and hydrogen. We can solve the ideal gas law for volume and hence treat the volume as a function of the pressure and temperature: V(P,T) = 8.314T P 1000 tells us about a key relationship between a) Explain in detail what the trace of V with P two quantities. b) Explain in detail what the trace of V with T = 5 tells us. c) Explain in detail what the level curve V = 0.5 tells us. d) Use 2 or 3 additional traces in each direction to make a rough sketch of the surface over the domain of V where P and T are non-negative.
