molar heat capacity वाक्य

Experiments confirmed the former prediction, but found that molar heat capacities of diatomic gases were typically about 5 cal / ( mol�K ), and fell to about 3 cal / ( mol�K ) at very low temperatures.
However, this law is inaccurate at lower temperatures, due to quantum effects; it is also inconsistent with the experimentally derived third law of thermodynamics, according to which the molar heat capacity of any substance must go to zero as the temperature goes to absolute zero.
This disagreement between the equipartition prediction and the experimental value of the molar heat capacity cannot be explained by using a more complex model of the molecule, since adding more degrees of freedom can only " increase " the predicted specific heat, not decrease it.
The "'molar heat capacity "'is the heat capacity per unit amount ( SI unit : mole ) of a pure substance and the "'specific heat capacity "', often called simply "'specific heat "', is the heat capacity per unit mass of a material.
A current student text on chemistry defines heat thus : " " heat " is the exchange of thermal energy between a system and its surroundings caused by a temperature difference . " The author then explains how heat is defined or measured by calorimetry, in terms of heat capacity, specific heat capacity, molar heat capacity, and temperature.
