Here we will answer the mostly asked question on zeroth law of thermodynamics on the internet. As we already discussed the zeroth law of thermodynamics in detail. We also discussed the application and examples of zeroth law. In that post we discussed all possible topics related to zeroth law of thermodynamics. But even we have to considered a lot. So here we will try to Answer of those questions which we left there.
These are the 10 plus Mostly asked Q&A on zeroth law of thermodynamics.
Q.1 What do you mean by zeroth law of thermodynamics?
Ans:- Zeroth law of thermodynamics states that if two thermodynamics system each are in thermal equilibrium with each other and connected with third (which is not in thermal equilibrium) then all the three system will be in thermal equilibrium.
Q.2 What are the application of zeroth law of thermodynamics?
Refrigerator is the best and common application of zeroth law of thermodynamics. Because in refrigerator the internal temperature not same as external temperature. That means there is a temperature difference. And we know that temperature difference is necessary for applicable of zeroth law of thermodynamics.
Q.3 What are the three laws of thermodynamics?
First law of thermodynamics:- according to this law energy is always conserved in nature. That means it can neither be created nor be destroyed but can be transfer from one to another form. Like heat energy can be converted into kinetic energy. please note that this is also called the law of conservation of energy.
Second law of thermodynamics:- it states that in a thermodynamics system, if it is isolated then and that total energy can never be decreasing with the passes of time. But this will happen only if all process are reversible.
Third law of thermodynamics:- it states that at zero temperature the entropy of a system will be constant. This is because of zero temperature. due to zero temperature the system become constant.
Please note that zero three of thermodynamics is also known as fourth law of thermodynamics.
Q.4 Why zeroth law is called so?
Zeroth law is called as zero law because h fowler give this name. And there is a miss confussion of giving this name. Some said fourth law or some one zero law but at last it has called as zeroth law.
Q.5 what is meant by entropy?
Entropy is the measurement of the amount of system thermal energy present in it. In other word it is the measuring of the amount of molecular disorder in a system.
