Question

a sample of helium gas has a volume of 1.00 l. what is the final volume if both the pressure and kelvin temperature each double?

Answer 1

If the both pressure and temperature of the helium gas is doubled, the final volume is 1.00 Liters.

What is the final volume of the helium gas?

Combined gas law put together both Boyle's Law, Charles's Law, and Gay-Lussac's Law. It states that "the ratio of the product of volume and pressure and the absolute temperature of a gas is equal to a constant.

It is expressed as;

P₁V₁/T₁ = P₂V₂/T₂

Given that;

• Initial volume V₁ = 1.00L
• Initial Pressure = P
• Initial temperature = T
• Final pressure = 2P
• Final temperature = 2T
• Final volume V₂ = ?

P₁V₁/T₁ = P₂V₂/T₂

P₁V₁T₂ = P₂V₂T₁

V₂ = P₁V₁T₂ / P₂T₁

V₂ = ( P × 1.00L × 2T ) / ( 2P × T )

V₂ = ( 2.00L × P × T ) / ( 2 × P × T )

V₂ = ( 1.00L × P × T ) / ( × P × T )

V₂ = 1.00L

If the both pressure and temperature of the helium gas is doubled, the final volume is 1.00 Liters.
