A 5.00L sample of helium expands to 12.0L at which point the pressure is measured to be 0.720 atm what is the original pressure of the gas ?

1.73 atm

Explanation:

Given data:

Volume = V1 = 5L

Volume = V2 = 12.0 L

Pressure P2 = 0.720 atm

To fnd:

Pressure P1 = ?

Formula:

By using Boyle's law,

P1 x V1 = P2 x V2

Calculation:

P1 = (P2 x V2) / V1

= 0.720 atm X  12.0 L  / 5L

= 8.64/5

= 1.73 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.
