Question

What happens to the entropy of water when it freezes? What happens to the entropy of water when it freezes? The entropy of water decreases when it freezes. The entropy of water can either decrease or increase when it freezes. It depends on the freezing conditions. The entropy of water remains constant when it freezes. The entropy of water increases when it freezes.

Answer 1

Water expands and becomes less dense when it freezes into ice. This means that ice floats in water instead of sinking

Step-by-step explanation:

Answer 2

The entropy of water decreases when it freezes.

Step-by-step 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 liquid is converted to solid entropy decreases,

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

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 randomness increase , and , the entropy will increase .

From , the question ,

The entropy of water decrease as it freezes .
