    option C The vapour pressure of water will remain same as the temperature is unchanged. Explanation- The vapor pressure of a liquid varies with its temperature As the temperature of a liquid or solid increases its vapor pressure also increases. Conversely, vapor pressure decreases as the temperature decreases. The pressure exerted by vapour over the surface of a liquid at a given temperature is called vapour pressure ...... it (v .p) increases exponentially with increase in temperature.... i.e, vapour pressure(v.p) is directly proportional to temperature... (v .p)1/(v .P)2=T1/T2. 0.4/(v .p)2=300k/300k. 0.4/(v .p)2= 1/1. (v .p)= 0.4
