Question

When water (H2O) freezes into ice, some of the properties have changed but the __________ of the H2O is the same.

A.identity
B. energy
C. arrangement
D.property

Answer 1

Answer: (A). When water freezes into ice, some of the properties have changed but the identity of the water is the same.

Step-by-step explanation:

We know that,

The physical state changes of the water but not the substance of the water.

Water is the liquid state, ice is the solid state of water and vapor is the gas state of water.

The identity of the water does not change in any state.

So. When water freezes into ice, some of the properties have changed but the identity of the water is the same.

Hence, A is the correct option.

Answer 2

Answer;

A. identity

When water (H2O) freezes into ice, some of the properties have changed but the identity of the H2O is the same.

Explanation;

• Water can exist in liquid, solid; ice and gaseous state; steam.
• Freezing occurs when water is continuously cool until it turns to solid ice, water freezes at zero degree Celsius.
• When water freezes the molecules of water have reduced their vibration speed, such that they are now arranged in fixed positions forming a solid.
• Water unlike most substances becomes less dense when it freezes, this explains why ice floats in water as it is less denser than water.
