The correct order of molar heat capacities measured at 298 K and 1 bar is :
A
Copper (s) > Bromine (l) > Helium (g)
B
Bromine (l) > Copper (s) > Helium (g)
C
Helium (g) 
Bromine (l) 
Copper (s)
Bromine (l) Copper (s) D
Helium (g) 
Bromine (l) = Copper (s)
Bromine (l) = Copper (s)
Text Solution
Verified by ExpertsThe correct answer is:
B
Generally molar heat capacity of liquids is greater than solids because liquids have greater degrees of freedom & thus can store more energy with lesser temperature rise.
Also, for monoatomic gases molar heat capacity is low as only translational degrees of freedom are present.
∴ order is :
