What is true about an ideal gas? -CORRECT ANSWERS-The volume of idealized Ne is different than idealized He at the same n, T, and P
If the temperature of a fixed sample of ideal gas is fixed and no reactions occur, what happens to the volume when the pressure is doubled? -CORRECT ANSWERS-The volume is decreased by a factor of 2
