The pressure in a constant-volume gas thermometer is 0.700 atm at 100^oC and 0.512 atm at 0^oC. (a) What is the temperature when the pressure is 0.0560 atm? (b) What is the pressure at 405^oC? An ideal gas is held in a...
A sample of 0.25 moles of an ideal gas expands from 72 milliliters to 10 liters. If the gas expands adiabatically against a constant pressure of 760 Torr, calculate the change in internal energy. A mole of an idea...
In reality, there are no ideal gases, but the ideal gas law can still be used to describe the basic behavior of a gas. This law states that PV = nRT, where P is the pressure, V is the gas volume, n is the number of moles of gas, R is the gas constant, and T...
b. For an isothermal process, PV = constant and for the given process PV^(2) = constant. Therefore has is cooled because volume expands by a greater exponent than is in an isothermal porcess.
