Answer:Gravity
Explanation:Gravity is the force that pulls everything down instead of up because if we didn’t have gravity we would be floating upwards
Answer:
n=2.053
Explanation:
We will use Snell's Law defined as:
Where n values are indexes of refraction and 
values are the angles in each medium. For vacuum, the index of refraction in n=1. With this we have enough information to state:
Solving for 
yields:
Remember to use degrees for trigonometric functions instead of radians!

The temperature where vapour pressure equals atmospheric pressure is called BOILING POINT. This vapour pressure increases with rise in temperature. Also boiling point is different for different liquids. Hope I cleared your doubt...
