Solution

The correct option is C The system absorbs heat and gains entropy.
Energy is used to form peptide bonds between amino acids to form the polypeptide. A bond contains stored form of energy/heat and therefore has greater entropy.
So, the correct answer is 'The system absorbs heat and gains entropy'

Q. Water flowing at the rate of 1 kg/s through a system is heated using an electric heater such that the specific entropy increases by 2.50 kJ/kg and the specific entropy increases by 0.007 kJ/kgK. the power input to the electric heater is 2.50 kW. There is no other work or heat interaction between the system and the surroundings. Assuming an ambient temperature of 300K, the irreversibility rate of the system is kW. (round off to two decimal places).

Q. Assertion :Heat added to a system at lower temperature causes greater randomness than when the same quantity of heat is added to it at higher temperature. Reason: Entropy is a measure of the degree of randomness or disorder in the system.
