Question

1) Which of the following option indicates extensive properties of the system?
O a) Specific enthalpy and internal energy
O b) Thermal conductivity and specific heat capacity
Oc) Temperature and pressure
O d) Enthalpy and entropy​

Answer 1

Answer:

option A is correct  

• specific enthalpy and internal energy are extensive properties.  

• extensive properties are those which are measurable it depends on the matter  

• examples =  volume, internal energy, Gibbs free energy, heat capacity these are the extensive properties.

• other options contain intensive properties,  

• intensive properties are those which does not depend on matter examples of intensive properties.

• temperature, pressure, refractive index, specific conductance, surface tension, volume, viscosity, molality  

• in the given option specific heat capacity, temperature, pressure, are all intensive properties.  so option A is correct.
