Stoichiometry Mcqs for Chemical


Q.  Pick out the wrong statement?

a. Atomic heat capacities of the crystalline solid elements are nearly constant and equal to 6.2 kcal/kg-atom according to the law of Petit and Dulong
b. Atomic heat capacities of all solid elements decrease greatly with decrease in temperature, approaching a value of zero at absolute zero temperature,
c. Generally, the heat capacities of compounds are lower in the liquid than in the solid state
d. The heat capacity of a heterogeneous mixture is an additive property, but when solutions are formed, this additive property may no longer exist
