Answer:
The new volume is 1.62 L
Explanation:
Boyle's law says:
"The volume occupied by a given gas mass at constant temperature is inversely proportional to the pressure." It is expressed mathematically as:
Pressure * Volume = constant
o P * V = k
Charles's law is a law that says that when the amount of gas and pressure are kept constant, the ratio between volume and temperature will always have the same value:

Gay-Lussac's law indicates that when there is a constant volume, as the temperature increases, the gas pressure increases. And when the temperature is decreased, the gas pressure decreases. So this law indicates that the quotient between pressure and temperature is constant.
Gay-Lussac's law can be expressed mathematically as follows:

Combined law equation is the combination of three gas laws called Boyle's, Charlie's and Gay-Lusac's law.

Having an initial state 1 and a final state 2 it is possible to say that:

Standard temperature and pressure (STP) indicate pressure conditions P = 1 atm and temperature T = 0 ° C = 273 ° K. Then:
- P1= 1 atm
- V1= 1.2 L
- T1= 273 °K
- P2= 0.80 atm
- V2= ?
- T2= 21°C= 294 °K
Replacing:

Solving:

V2= 1.62 L
<u><em>The new volume is 1.62 L</em></u>
<u><em></em></u>
Because food and water are resources that are basic needs for all members of the population. When these resources decrease more members of the population will either die or move to another area and the population size will decrease.
Hope this helps!
