The temperature in the flask in kelvin is 577.3 K.
The relationship between volume, temperature, moles and pressure of a gas is given by the ideal gas equation written below:
where;
For the gas:
P = 120 kPa
n = 0.25 moles
V = 10 dm³
R = R = 8.314 dm³.kPa/mol.K
T = ?
T = PV/nR
T = 120 * 10/8.314 * 0.25
T = 577.3 K
