Acontainer contains 5l of nitrogen gas at 25 degrees celsius. what will be it’s volume if the temperature increases by 35 degrees?

Charles law gives the relationship between volume and temperature of gas. 
it states that at constant pressure volume of gas is directly proportional to temperature.

where V - volume 
T - temperature in kelvin
and k - constant

where parameters for the first instance are on the left side and parameters for the second instance are on the right side of the equation 
T1 - 25 °C + 273 = 298 K
T2 - 35 °C + 273 = 308 K
substituting the values in the equation 

V = 5.17 L
new volume is 5.17 L
