Question
An ideal gas of one mole is kept in a rigid container of negligible heat capacity. If 25 J of heat is supplied the gas temperature raises by 20 C. Then the gas may be
Options
A.helium
B.argon
C.oxygen
D.carbon dioxide
Solution
ᐃQ = ᐃU + ᐃW ⇒ 25 = 
+ 0
25 =
f = 3 (monoatomic)
+ 025 =
f = 3 (monoatomic)
