Q. What is the relative humidity for a saturated air?

On a winter day, the outside temperature is $0^{0}$ C and relative humidity 40 %. The air from outside comes into a room and is heated to $20^{0}$ C. What is the relative humidity in the room ? The saturation vapour pressure at $0^{0}$ C is 4.6 mm of mercury and at $20^{0}$ C it is 18 mm of mercury.

Q. Choose the best option based on the four statements given below.

1. Saturation level is the point at which the relative humidity is 70%.

2. Orographic rainfall is more commonly seen in mountainous regions.

3. Cumulus clouds are formed at a height of 4,000 to 7,000 m.

4. Temperature does not affect the humidity of a place.

Q. On a winter day, the outside temperature is 0°C and relative humidity 40%. The air from outside comes into a room and is heated to 20°C. What is the relative humidity in the room? The saturation vapour pressure at 0°C is 4.6 mm of mercury and at 20°C it is 18 mm of mercury.

The temperature and the relative humidity are 300 K and 20 % in a room of volume 50 m a. The floor is washed with water, 500 g of water sticking on the floor. Assuming no communication with the surrounding, find the relative humidity when the floor dries. The changes in temperature and pressure may be neglected. Saturation vapour pressure at 300 K = 3.3 kPa.
