Answer:
The gravitational pull of a black hole is so strong that nothing, not even light, can escape once it gets too close. ... Moving at close to the speed of light, these particles ricochet off the event horizon and get hurled outward along the black hole's axis of rotation
(True)
The answers that apply are;
- gas molecules are closer together
- air weighs more
- air is hotter
When air is compressed, it means the same volume of space is occupied by more air molecules. This, therefore, means that the molecules are hitting each other with a higher frequency hence become hotter with more compression. It weighs more because there are more molecules in the same volume of space.
