Question

A sample of hydrogen gas at 2.0 atmospheres and 273 k occupies a volume of 5.0 liters. the gas sample is completely transferred to a 10.0-liter sealed, rigid container. what is the new pressure of the gas sample when the temperature returns to 273 k?

Answer 1

Boyle's law gives the relationship between pressure and volume of gas, It states that for a fixed amount of gas when the temperature is kept at a constant value, pressure is inversely proportional to volume of gas.
PV = k
where P - pressure, V - volume and k - constant 
p1v1 = p2v2
where parameters for the first instance are on the left side and parameters for the second instance are on the right side of the equation 
2.0 atm x 5.0 L = P x 10.0 L 
P = 1.0 atm
new pressure is 1.0 atm

Answer 2

The new pressure of the gas sample when the temperature returns to 273 k is 1.0 atm.

What is Boyle's law?

Boyle's law states that volume and pressure have an inverse relationship.

By Boyle's law

$\rm P_1V_2= P_1V_2$

putting the values

2.0 atm × 5.0 L = P × 10.0 L

$P_2$ = 1.0 atm.

Thus, the new pressure of the gas is 1.0 atm.
