Answer:

Pretty sure it's true.

On Earth, we only see part of the moon that is illuminated or not, since it revolves around the Earth. However, the sun is stationary and doesn't move, meaning that one side of the moon is always lit by the sun as it revolves around the Earth.

A SCUBA tank can normally hold 18 liters of gas at 3000 psi. How many liters of gas would this be equivalent to if the gas were
NikAS [45]

Liters of gas at 14.7 psi: 3674 L

Explanation:

We can solve this problem by using Boyle's law, which states that:

"For an ideal gas kept at constant temperature, the pressure of the gas is inversely proportional to its volume"

Mathematically:

pV=const.

where

p is the gas pressure

V is its volume

This law can also be rewritten as

p_1 V_1 = p_2 V_2

Where:

p_1 = 3000 psi is the initial pressure of the gas

V_1 = 18 L is the initial volume of the gas

p_2 = 14.7 psi is the final pressure of the gas

V_2 is the final volume

Therefore, we can calculate the volume of gas corresponding to 14.7 psi of pressure:

V_2=\frac{p_1 V_1}{p_2}=\frac{(3000)(18)}{14.7}=3674 L
