Q1: A saturated vapor on being compressed would

ANS:C - both (a) & (b)

When a saturated vapor is compressed, its pressure increases. This increase in pressure can lead to different outcomes depending on the conditions and the properties of the vapor:

1. Condense: If the pressure increase causes the vapor to exceed its saturation pressure at the given temperature, condensation will occur. The vapor will condense into a liquid phase.
2. Form wet steam: Wet steam is a mixture of water vapor and liquid water. When a saturated vapor is compressed, it can result in the formation of wet steam if the pressure increase is not sufficient to cause complete condensation of the vapor. Instead, some of the vapor remains in the gas phase while some condenses into liquid phase, forming wet steam.
