A gas occupies 12.2 liters at 0.8 atm. What is the pressure if the volume becomes 15.6 L?

The pressure is 0, 63 atm

Explanation:

We use Boyle Mariotte's formula: for a given mass of gas at constant temperature, the pressure and volume vary inversely proportionally:

P1xV1= P2xV2

P2=(P1xV1)/V2= (0,8 atmx 12, 2 L)/15, 6 L=0,63 atm

they all get energy from eating other animals, dead animals to be more precise.

hienas tends to steal pray from other animals. crows and vultures tend to eat dead animals and leftovers.
