During puberty, you can expect physical changes such as growth spurts, development of secondary sexual characteristics (breast development in girls, facial hair in boys), voice changes, increased sweat and body odor, and acne due to hormone fluctuations. Puberty can vary in timing and intensity for each individual.
All changes in a phase are physical changes. These changes involve a rearrangement of the particles in the substance, but the actual particles themselves remain the same.
Some examples of physical changes are changes in state (solid, liquid, gas), changes in shape or size, changes in color, changes in texture, and changes in temperature.
Examples of physical changes include melting of ice, boiling of water, cutting a piece of paper, breaking a glass, and dissolving salt in water. These changes alter the form or appearance of a substance without changing its chemical composition.
Scientists use a variety of methods, such as microscopy, spectroscopy, chromatography, and mass spectrometry, to identify physical changes in materials. These techniques help scientists observe changes in the size, shape, structure, composition, or properties of a substance, allowing them to understand how physical changes occur at a molecular level.
Physical changes in girls can include the development of breasts, the growth of pubic hair and underarm hair, menstruation, and changes in body shape as they go through puberty. These changes are a part of the natural process of maturation and development during adolescence.

Physical Changes
The average age for girls (physical changes) is 10-11, but puberty may show from ages as young as 8 to as old as 14.
During puberty, both boys and girls experience physical changes such as growth spurts, development of secondary sexual characteristics (like facial hair in boys and breast development in girls), and hormonal changes leading to sexual maturity. Hormones like testosterone and estrogen play a key role in these changes, which usually occur between the ages of 10 and 14 for girls and 12 and 16 for boys.

There is an increase in the size of the testis in males. There is onset of menstruation in girls.
There are no physical changes. there are only chemical changes.
Reversible changes and physical changes are not exactly the same. Reversible changes can be undone and the original substance can be recovered, while physical changes alter the appearance or state of a substance without changing its chemical composition. Physical changes are usually reversible, but not all reversible changes are physical changes.
