Which statement best describes the difference between a physical change and a chemical change?

a chemical change results in a new element being formed, and a physical change results in a new compound being formed.

a physical change is a change from one state of matter to another; a chemical change results in a new substance formed.

a chemical change does not result in a new substance being formed, whereas a physical change does.

a physical change produces a new element, and a chemical change results in a bond breaking between atoms.

A physical change is a change from one state of matter to another; a chemical change results in a new substance formed.

Explanation:

Physical Change:                                                                                              

The changes that occur only due to change in shape or form but their chemical or internal composition remain unchanged.

These changes were reversible.

They have same chemical property.

These changes can be observed with naked eye.

Example :

Water converting to Ice

Water converting to gas

In this water molecule remain the same only they rearrange themselves that change its state of mater not composition

Chemical change:

The changes, that occur due to change in the composition of a substance and result in a different compound is known as chemical change.

These changes are irreversible

These changes occur due to chemical reactions

These may not be observed with naked eye

Example:

Combustion of fuel or wood: that oil or wood convert into energy, CO₂ and ash in case of wood

Boiling of egg: that change the chemical composition of protein in the egg

The reaction of Hydrogen and oxygen:

2H₂ (g)  + O₂  (g) > 2H₂O  (l)
