This set of Physics Multiple Choice Questions & Answers (MCQs) focuses on “Zeroth Law of Thermodynamics”.
1. Zeroth law of thermodynamics can be derived. It is not based on observation. True or False?
a) True
b) False
View Answer
Answer: b
Explanation: The zeroth law of thermodynamics is based purely on observation. This law may seem obvious but if a person, A, knows B & B knows C it’s not at all necessary for A to know C.

2. Zeroth law of thermodynamics helped in the creation of which scale?
a) Temperature
b) Heat energy
c) Pressure
d) Internal energy
View Answer
Answer: a
Explanation: Zeroth law of thermodynamics talks about thermal equilibrium or relates bodies having no heat flow. Temperature difference is what leads to heat flow. So, this law helped in making temperature measurable and an universal property of matter.
