Answer:
The statement is false.
Explanation:
Fundamental dimensions are those dimensions that cannot be derived from any combination of physical quantities in the universe and these quantities act as base quantities from which all other physical quantities are derived.
The fundamental dimensions in the nature are:
1) Length (L)
2) Mass (M)
3) Time (T)
4) Current (A)
5) Temperature (K)
6) Amount/ Quantity (MOLE)
7) Luminous intensity (CANDELA)
All the other physical quantities are derived from a combination of these fundamental dimensions.
Power can be represented as and hence it is a derived quantity.
Answer:
Entropy:
Entropy is the measure of randomness of system.In other words the entropy is the measurement of tendency of system towards the disorder.
The concept of entropy arise from second law of thermodynamics.It is given as follows
Entropy is a extensive property of system .
Entropy of universe = Entropy of system + Entropy of surrounding.
The entropy of the system can be zero,positive and negative.But entropy of the surrounding can not be negative,but it can be zero or positive.
Actually the concept of entropy is difficult to understand because we can not visualize because it is not like beam and like rods.Only we have to realize that there is entropy.
