Hey how would I solve this? Three moles of a monatomic ideal gas are heated at a constantvolume of 2.21 m3. The amount of heat added is 5.16 x103 J. (a) What is the change in thetemperature of the gas? (b) Find the change in itsinternal energy. (c) Determine the change inpressure. Thank you! Hey how would I solve this?

(b) Find the change in itsinternal energy. (c) Determine the change inpressure. Thank you!Explanation / Answer
At constant volume heat added is equal to changein internal energy . which is a isomeric process So U = 5.16*103 J work done in isomeric process is zero . change in internal energy U = ( 3 / 2 ) n R T for three moles n = 3 universal gas constant R = 8.31 J / mol . K change intemperature T = ( 2 / 9 )(5.16*103 J ) / 8.31 = 137 K
