Question #136155

A child releases a 6.25L helium balloon in the parking lot of an amusement park where the temperature is 28.50oC and the air pressure is 757.2mmHg, what will be the volume of the balloon when it has risen to an altitude where the temperature is -34.35oC and the air pressure is 366.4mmHg?

Answer

P₁V₁/T₁=P₂V₂/T₂

P₁=Initial pressure

V₁= Initial Volume

T₁= Initial temperature in Kelvin

P₂= Final pressure

V₂= Final temperature in Kelvin

T₂= Final temperature in Kelvin

P₁V_1/ T_{1 =} P₂V_2/ T₂

V₂ = (P₁V₁ T₂) ÷ P₂ T₁

   = (757.2mmHg×6.25L×238.65K) ÷ (366.4mmHg×301.5K

   = 10.2L
