Question

Zeroth law of thermodynamics gives the concept of
A- pressure
B- volume
C- temperature
D- heat

Answer 1

Hint: Thermodynamics is a branch of science which deals with the transfer of heat and its associated. There are three laws of thermodynamics, zeroth law, first law & second law. It was discovered after the first law and second law was discovered so it was named as zeroth law.

Complete step by step answer:
According to the zeroth law of thermodynamics, if a system P is in equilibrium with a system Q and also it is in thermal equilibrium with the system R, then both system Q and system R are also in thermal equilibrium with each other. This statement put forth the zeroth law of thermodynamics. The law is based on temperature. So, the zeroth law gives the concept of temperature

So, the correct answer is “Option C”.

Additional Information:
Temperature is a measure of the hotness or coldness of the body. To measure the degree of hotness or coldness of a body, we use different scales and the choice of scale depends upon the purpose of measurement. The Fahrenheit and the Celsius scale are used in laboratories while doing experiments and all.

Note:
Another way of stating the zeroth law is if two systems are in thermal equilibrium with each other then the temperature of both the systems will be equal. The zeroth law is one of the most important laws when read with the first law of thermodynamics.
