On what factors do the temperature of a substance depends?
Answer to Problem 1MCPE
Solution:
Correct option is (c).
Temperature is generally proportional to substance’s average translation kinetic energy.
Explanation of Solution
Temperature determines hotness or coldness of an object or surrounding.
All particles within the substance are continuously in a state of motion. These particle shows vibrational as well as translational motion.
These particles vibrate continuously inside a substance, but translational motion is observed only when particles are excited from the ground state to higher energy level. This energy is gained due to external heat from the atmosphere.
Hence, temperature is dependent on average translational kinetic energy.
Conclusion:
Temperature of the substance is dependent on average translational kinetic energy.
