Gas Law Problem #5

Question

A gas occupies 900.0 mL at a temperature of 27.0 degrees Celsius. What is the volume at 132.0 degrees Celsius? - Use an Equation - Show All Work

Answer 1

If the pressure of the gas is constant, we can use Charles' law:

 

V₁ / T₁ = V₂ / T₂

 

V₂ = (T₂ / T₁) V₁

 

Use absolute temperature (Kelvin).

 

T₁ = 27.0°C = (27.0 + 273.0) K = 300.0 K

 

T₂ = 132.0°C = (132.0 + 273.0) K = 405.0 K

 

V₁ = 900.0 mL

 

V₂ = (405.0 / 300.0) (900.0) mL = 1215 mL
