## What is meant by entropy increasing?

Entropy increases as temperature increases. An increase in temperature means that the particles of the substance have greater kinetic energy. The faster moving particles have more disorder than particles that are moving more slowly at a lower temperature.

## How does entropy affect the environment?

The greater the entropy, the greater the losses, waste, and environ- mental impact—everything from heated waterways and degraded air quality to land contamination. We may, however, be able use that fundamental insight to help us plan our energy future and tackle greenhouse gas pollution.

## Which is the best example of increasing entropy?

The entropy increases when more energy is put into a system that excites the molecule and the amount of random activity. Hence, cyclist pedalling harder while riding uphill is the example of entropy.

## What happens when entropy decreases?

The total entropy of a system either increases or remains constant in any process; it never decreases. For example, heat transfer cannot occur spontaneously from cold to hot, because entropy would decrease. Entropy is very different from energy. Entropy is not conserved but increases in all real processes.

## What causes entropy to decrease?

When a small amount of heat ΔQ is added to a substance at temperature T, without changing its temperature appreciably, the entropy of the substance changes by ΔS = ΔQ/T. When heat is removed, the entropy decreases, when heat is added the entropy increases. Entropy has units of Joules per Kelvin.

## What does entropy depend on?

The entropy of a substance increases with its molecular weight and complexity and with temperature. The entropy also increases as the pressure or concentration becomes smaller. Entropies of gases are much larger than those of condensed phases.

## What is the difference between entropy and chaos?

Entropy is basically the number of ways a system can be rearranged and have the same energy. Chaos implies an exponential dependence on initial conditions. Colloquially they can both mean “disorder” but in physics they have different meanings.

## What state has highest entropy?

Gases

## Which has least entropy?

Diamond
