Matter is always changing to different states of matter. Ice melts into water, water boils into steam(gas), and frost can form on a cold window. Even though these are just a few examples, there are many more phase

Entropy (s) is a measure of how dispersed energy is or how many possible arrangements particles in a system can have. Systems naturally move towards states with higher entropy, which are more probable. Important ideas to remember about entropy are that entropy increases with disorder or energy
