Answer:
The condition of very system can be identified by some physical characteristics of the system known as Thermodynamic Property of the system. For example, pressure, temperature, volume, etc.
Explanation:
Thermodynamic properties are nothing but the physical characteristics of any body by which the physical condition of the body can be described. properties describes the different states of a system. They are macroscopic.
Properties are of two types ---
Intensive property
Extensive property
Intensive Property : Those properties of a system which does not depend upon mass of the system are known Intensive property.
For example, pressure, temperature, density,specific volume, etc
Extensive Property : Properties that depends on the mass oh the system is called Extensive properties.
For example, energy, volume, etc.

Answer:
(a) Work done is 1.59642 kJ
(b) Useful power supplied = 0.1298 kW
Explanation:
(a) Work done = mass of crate × acceleration due to gravity × distance = 90.5 kg × 9.8 m/s^2 × 1.8 m = 1596.42 kgm^2/s^2 × 1 J/1 kgm^2/s^2 × 1 kJ/1000 J = 1.59642 kJ
(b) Useful power supplied = work done ÷ time = 1.59642 kJ ÷ 12.3 s = 0.1298 kJ/s × 1 kW/1 kJ/s = 0.1298 kW
