Answer:
246.28 K
Explanation:
The total energy of one mole of gas molecules can be calculated by the formula given below
E = [tex]\frac{3}{2}\times R\times T[/tex]
Where R is gas constant and T is absolute temperature.
Put the value of R as 8.314 and temperature as 245 , we get
E = [tex]\frac{3}{2}\times 8.314\times 245[/tex]
= 3055.4 J
Add 16 j to it
Total energy of gas molecules = 3055.4 + 16 = 3071.4 J.
If T be the temperature after addition of energy then
[tex]\frac{3}{2}\times 8.314\times T[/tex] = 3071.4
T =[tex]\frac{2\times 3071.4}{3\times 8.314}[/tex]
T = 246.28 K
