(a)
Interpretation: The final temperature of the system has to be calculated.
Concept introduction: The physical quantity which is the ratio of the amount of heat transferred to a substance and the increase in temperature is called heat capacity. If it is measured for one mole of substance, it is known as molar heat capacity.
(b)
Interpretation: The heat transferred to the copper block has to be calculated.
Concept introduction: The physical quantity which is the ratio of the amount of heat transferred to a substance and the increase in temperature is called heat capacity. If it is measured for one mole of substance, it is known as molar heat capacity.
(c)
Interpretation: The entropy change of the copper block, water and total system has to be calculated.
Concept introduction: The randomness present in the system is called its entropy. It is an extensive property. At equilibrium, the entropy of the system is zero. It is denoted by
