Define specific heat of a substance.
It is the amount of heat required to raise the temperature of 1 gram of a substance through l°C.
Define molar heat capacity of a substance.
What is the mode of transference of energy, when petrol is subjected to combustion in an internal combustion engine ?
It is a partly as work and partly as heat.
Define heat capacity of a system.
It is the amount of heat required to raise the temperature by one degree celcius or kelvin. It is expressed in units of thermal energy per degree temperature.
Differentiate between molar heat capacity and molar solution.
Molar heat capacity: Molar heat capacity means the amount of heat absorbed by one of the substance to raise its temperature through 1°.
Molar solution. The molar solution means a solution containing one mole of the solute per litre of the solution.
