Concept Introduction:
The first law of
Heat absorbed or released by a system is calculated by multiplying the mass of the substance with its specific heat and the change in temperature of the system.
The sign of heat change is positive, if heat is absorbed by the system, and negative, if heat is released by the system.
The specific heat (s) of a substance is the amount of heat required to raise the temperature of 1 g of the substance by
The heat released by the system in the given system is calculated by the formula
Here,
The heat absorbed by the substance in the given system is calculated by the expression:
Here,
The conversion of volume from
The conversion of heat from
The number of moles of solute present in the given solution is calculated by the formula,
Here,
