Q1: In chemical dehumidification of air

ANS:C - specific humidity decreases & dry bulb temperature increases.

In chemical dehumidification of air, the process involves removing moisture from the air. Here's how specific humidity and dry bulb temperature change during this process:

• Specific humidity refers to the actual amount of water vapor present in the air. When air is dehumidified, the specific humidity decreases because moisture is being removed from the air.
• Dry bulb temperature refers to the temperature of the air without consideration of humidity. During dehumidification, the dry bulb temperature typically increases because the removal of moisture from the air can cause a slight increase in temperature due to the release of latent heat.
