1. Condensation of a liquid causes cooling False
2. At high altitudes, water boils above 100°C. T31
3. Gases have a fixed shape and definite volume.​

Answer 1

Explanation:

A) False

B) True

C) False

Answer 2

Answer:

1. True

2. False

3. False

Explanation:

1.While condensation does cool the air inside of the air parcel, in order for that cooling to occur, that parcel must release heat into the surrounding environment. ... In order for condensation to happen, the water vapor molecules must release energy so that they can slow their movement

2. The reason is the lower atmospheric pressure due to a thinner blanket of air above. ... As atmospheric pressure decreases, water boils at lower temperatures.

3. Particles are far apart from each other because there are very weak forces of attraction between them. They move fast in all directions. Because of this, gases don't have a definite shape or volume and fill any container. Because there is lots of free space between particles, gases can easily be compressed.
