Question
Confusing after a while.
True or False
A. if the number of moles of gas in a container is increased, the gas molecules will attract one another and the pressure will be decreased.
B. If the temperature of a gas is increased, its volume must increase if the pressure is to be kept constant.
C. As temperature increases, the volume of a gas always increases, even if the pressure is not kept constant.
D. When the volume and the kelvin temperature of an ideal gas are both doubled, the pressure of the gas is doubled.
E. When the pressure of and ideal gas is doubled and its volume is cut in half, its kelvin temperature will remain the same.
Explanation / Answer
ideal gas obey gas law,
PV = nRT
where P=pressure, V =volume , n= no. of mole , R = gas constant ,T = absolute temperature in kelvin
