Question

PLEASE HELP ME I BEG YOU

The average kinetic energy of 1 mole of a gas at -32 degrees Celsius is:
3.01 x 103 J
3.99 x 102 J
-3.99 x 102 J
3.80 x 103 J

The relationship between volume and temperature of a gas, when pressure and moles of a gas are held constant, is: V*T = k.

TRUE
FALSE

The relationship between moles and volume, when pressure and temperature of a gas are held constant, is: V/n = k. We could say then, that:
If the moles of gas are tripled, the volume must also triple.
If the moles of gas are halved, the volume must be doubled.
If the moles of gas are doubled, the volume must be halved.
If the moles of gas are doubled, the volume is unaffected.

If the temperature and volume of a gas are held constant, an increase in pressure would most likely be caused by an increase in the number of moles of gas.

TRUE
FALSE

If the vapor pressure of a liquid is less than the atmospheric pressure, the liquid will not boil.

TRUE
FALSE
