Question

B) State right (V) or wrong (x): 1. The internal energy in the cyclic process has constant value. 2. An adiabatic system is one which cannot transfer energy but transfer matter to and from its surrounding. 3. Heat of combustion could be used in calculation of the heat of formation. 4. An isochoric process takes place at constant concentration.​

Answer 1

1. False. The internal energy of a system can vary during a cyclic process.

2. False. An adiabatic system is a system that does not exchange heat with its surroundings. It may still be able to transfer matter or energy in other ways.

3. True. The heat of combustion is the amount of heat produced when a substance is burned. It can be used to calculate the heat of formation, which is the heat absorbed or released when a substance is formed from its elements.

4. False. An isochoric process is a process that takes place at constant volume. It does not necessarily involve a change in concentration.
