heat energy simple answer

I hope its help you please mark me as brainlist

Answer 2

Answer:

1.432U

Explanation:

GIVEN- An ideal gas with internal energy u at 200oc is heated to 400oc.

FIND- internal energy

SOLUTION-

The internal energy of an ideal gas is proportional to the thermodynamic (absolute) temperature of the gas.

200 C = 473.15 K,

400 C = 673.15 K

(U at 400C)/U = 763.15K / 473.15 K = 1.423.

The internal energy at 400 C is 1.423 * U.

FINAL ANSWER- 1.432U
