Question

What factor affecting entropy of system?

Answer 1

Factors affecting entropy of a system are :-

• Temperature increases entropy increases
• Pressure increase entropy decreases
• Molar mass increase entropy increase
• Volume increases entropy increases
• Number of moles increase so entropy also increases

Answer 2

The factor affecting the entropy of the system is:

• Entropy is the randomness possessed by molecules or the system.
• When randomness increases entropy is positive, when decreases entropy is negative.
• In the free expansion gas moves freely and molecules tend to escape out.
• An increase in temperature increases the entropy as disorders increase while temperature decreases causing a decrease in entropy.
• In compression entropy of the system is negative as the gas molecules come nearer and the volume decreases, which decreases the randomness.
• During expansion, volume increases so molecules get enough space for movement. An example of free expansion is an explosion of the cylinder.
