Question

A gas sample has a volume of 150 ml at 0.00 ∘c. the temperature is raised (at constant pressure) until the volume is 218 ml. what is the temperature of the gas sample in ∘c at this volume?

Answer 1

Charles law gives the relationship between volume and temperature of a gas.
It states that at constant pressure, volume is directly proportional to temperature of gas.
V/ T = k
where V -volume , T - temperature and k - constant

`(V1)/(T1) = (V2)/(T2)`
parameters for the first instance are given on the left side and parameters for the second instance are given on the right side of the equation
T1 - temperature in kelvin 0.0 °C + 273 = 273 K
substituting the values in the equation

`(150 mL)/(273 K) = (218 mL)/(T)`
T = 397 K
temperature in celcius - 397 K - 273 = 124 °C
new temperature is 124 °C
