A sample of a fixed mass of an ideal gas is enclosed in a rigid, sealed container of constant volume. The gas is heated such that its thermodynamic (Kelvin) temperature quadruples.
Which row correctly identifies two physical quantities of the gas that both increase by a factor of 4?
First Quantity: Pressure of the gas | Second Quantity: Root-mean-square (rms) speed of the molecules
First Quantity: Mean kinetic energy of the molecules | Second Quantity: Internal energy of the gas
First Quantity: Pressure of the gas | Second Quantity: Density of the gas
First Quantity: Density of the gas | Second Quantity: Mean kinetic energy of the molecules
