The volume of a gas is increased from 100mL to 250 mL by heating it.If the original temperture of the gas was 15.0°c what will be the final temperture in °c

Answer 1

(V1/T1) = (V2/T2)
Remember T must be in kelvin

Answer 2

the volume increased by a factor of 2.5

the volume is directly proportional to the absolute (Kelvin) temperature

ºK = ºC + 273
