उत्तर
A triatomic molecule can be modelled as three rigid sphere joined by three rigid rods forming an triangle. Consider a triatomic gas consisting such molecule. If gas performs 30 J work when it expands under constant pressure the heat given to gas is 120 J.
Explanation:
`(Delta"Q")/"W" = "C"_"p"/"R"`
Cp = `("f"/2+1)`R (f = degree of produce)
= 4R
∴ ΔQ = 4W = 120 J
