What is relationship between specific heat capacity of water and molar gas constant
Answers
Definition 1: specific heat capacity is the amount of heat that is required to raise the temperature of one kilogram of a fixed mass of a substance thru one Kelvin at constant pressure. [We can also consider the specific heat capacity that of a gram.] The unit for Specific Heat therefore is: joules / gram-K.
Definition 2: molar heat capacity is the heat required to raise the temperature of one mole of a substance thru one Kelvin at constant pressure. The unit for Molar Heat therefore is: joules / g-mole-K.
One gram of a substance contains 1 /( g-molar mass) of the substance. We can form a ratio between the two definitions and notice that there is a proportion: The proportion tells us Specific Heat and Molar heat are related by the ratio of molecules present to Avogadro’s number
