If universal gas constant is R, the essential heat to increase from K

1.	If universal gas constant is R, the essential heat to increase from K to 473 K at constant volume for ideal gas of 4 moles isA. 200 RB. 400 RC. 800 RD. 1200 R
Answer» Correct Answer - D Specific heat for a monoatomic gas `C_(v)=(3)/(2)R` `therefore"Heat "dQ=muC_(v)DeltaT` `dQ=muxx(3)/(2)xxR(473-273)` = `4xx(3)/(2)xxRxx200" " (becausemu=4)` `therefore" " dQ=4xx300R=1200R`
