Two days the air parcels started with water vapor. It didn't rain Day 1 but rained at night on Day 2. Why?

• Air parcel was cooler than air on Day 2 so it gained energy on Day 2

• Air parcel was warmer than air on Day 2 so it gained energy on Day 2

• Air parcel was warmer than air on Day 2 so it lost energy on Day 2

• AIr parcel was at the same low temperature as the air so it had low energy
