Agas is confined in a steel tank with a volume og 6.982l at 20.20c the gas exerts a pressure of 8.532 atm. after heating the tank the pressure of gas increases to 10.406atm. what is the temperature of the heated gas convert celsius temp to kelvins

To solve this we assume that the gas is an ideal gas. Then, we can use the ideal gas equation which is expressed as PV = nRT. At a constant volume and number of moles of the gas the ratio of T and P is equal to some constant. At another set of condition, the constant is still the same. Calculations are as follows:

T1/P1 = T2/P2

T2 = T1 x P2 / P1

T2 = (20.20+273.15) x 10.406 / 8.532

T2 = 357.782 K or 84.632 C

i think its 100

i hope this !
