Question

A container contains 5L of nitrogen gas at 25 degrees Celsius. What will be it’s volume if the temperature increases by 35 degrees?

Answer 1

if 1 celcius=273 kelvin
25+273=298
35+273=308

so,

`(5)/(298) = (?)/(308)`
?=5.1677k

Answer 2

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.

`(V)/(T) = k`
where V - volume
T - temperature in kelvin
and k - constant

`(V1)/(T1) = (V2)/(T2)`
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

`(5L)/(298K) = (V)/(308K)`
V = 5.17 L
new volume is 5.17 L
