The natural tendency is for entropy to over time.

a) decrease
b) increase
c) remain constant
d) constantly fluctuate

quiz!

answer: option (b) is the correct answer.

explanation:

entropy is defined as the degree of randomness. this means that in an isolated system the particles will be in disorder.

it is an extensive property and depends on the mass of system. it does not depend on the path through which the process has taken place.

entropy increases because heat supplied to the substance or heat absorbed by the particles from the surrounding irrespective of temperature change.

thus, we can conclude that the natural tendency is for entropy to increase over time.

explanation:

earth's surface is mainly heated by the absorption of infrared radiation from the sun.

evaporation occurs because molecules in liquid water are warmed ( usually by the sun) and vibrate quicker, becoming less dense and rise.

condensation occurs because molecules in water vapor are cooled and therefore vibrate more slowly thus becoming more dense and eventually fall to earth.

lines of equal barometric pressure on a weather map are called: isobars : lines of equal temp on a weather map are called: isotherms.​

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
