A sample of gas is held at 100oc at a volume of 20 L. if the volume is increased to 40 L what is the new temperature of the gas in celcius.

470 °C  

Explanation:

This looks like a case where we can use Charles’ Law:  

Data:

V₁ = 20 L; T₁ = 100 °C

V₂ = 40 L; T₂ = ?  

Calculations:

(a) Convert the temperature to kelvins

T₁ = (100 + 273.15) K = 373.15 K

(b) Calculate the new temperature

Note: The answer can have only two significant figures because that is all you gave for the volumes.

(c) Convert the temperature to Celsius

T₂ = (750 – 273.15) °C = 470 °C

d.) the average kinetic energy of the gas particles is greater in container b because its particles move faster.
