(B) The vapor pressure decreases. (C) The vapor pressure stays the same. (D) The vapor pressure may increase or decrease, depending on the liquid.
Explanation / Answer
16.
option A is correct answer
in general at Low pressure and higher temperature gas behvae like a ideal gas
in order to act as a ideal gase
intermolecular forces should be much lower than kinitic energy of the gaes
taht is possible at very low pressure and higher T
at low pressure molecules are as far as possible
at high temperature kinitic energy of the molecule is higher
