State one law that holds good in all natural processes.
Answers
Answer ⇒ Zeroth law of thermodynamics.
Explanation ⇒ There are many laws in Physics which holds good in many natural process.
One of the common and basic law of our nature is the Zeroth, first and second law of thermodynamics.
Zeroth law of Thermodynamics ⇒ If two bodies let A and B are in thermal equilibrium (Same temperature, pressure, etc.) with each other, and Body B and C are in thermal equilibrium with each other, then A and C will also be in thermal equilibrium with each other.
It has many applications in Environment.
Similarly, First law of thermodynamics is also basic law of our nature.
Acc. to it, Energy can neither be created nor be destroyed , it can only be converted into one form to another.
If you will study this in higher classes, this law will say, energy transferred to any body can either increase its Internal energy or can done some work on it.
''Acc. to second law of thermodynamics, energy of system remains constant whereas Entropy (means randomness) always increases. ''
Hope it helps.
