What is the effect of temperature and pressure on viscosity of liquid and gases?

Vapour pessure of a liquid or a solution is the pressure exerted by the vapour in equilibrium with the liquid or solution at a particular temperature. It depends upon the nature of the liquid and temperature. It depends upon the nature of the liquid and temperature. According to Raoult's law in a solution, the vapour pressure of a component at a given temperature is equal to the mole fraction of that component in solution multiplied by the vapour pressure of that component in hte pue state. this solution in which each component obeys Raoult's law are called ideal solutions. there are two types of non ideal solutions, showing positive deviations and negative deviations from ideal behaviour. If liquid A and B form ideal solution, then
