Explanation:

Entropy -

In a system, the randomness is measured by the term entropy .

Randomness basically refers as a form of energy that can not be used for any work.

The change in entropy is given by amount heat per change in temperature.

When solid is converted to gas entropy increases,

As the molecules in solid state are tightly packed and has more force of attraction between the molecules, but as it is converted to gas, the force of attraction between the molecule decreases and hence entropy increases.

So,

The particles of the substance , if are tightly held by strong force of attraction will decrease the entropy ,

And

If the particles are loosely held , the entropy will increase .

I. Dry ice vaporize in a closet ,

Dry ice is in solid state , and gets converted to gaseous state , and hence , entropy increases .

V. Cake mix is manufactured from five basic ingredients -

The cake mix are semi - solid in nature and during the process of baking of cake , the cake batter gets flushes with air and hence , create a lot of space and makes the cake spongy , and hence , the entropy increases .

a graduated cylinder.

explanation:

its going to be mutualism cuz they both benefit from the relationship.
