When a physical change occurs in a sample of matter which is the matter that does not change?
During a physical change, the chemical composition of the matter remains the same, while its physical properties, such as shape, size, or state, may change. The individual particles that make up the matter do not change in a physical change.
Does a physical change occurs when matter changes state?
Yes, a physical change occurs when matter changes state. This change is reversible and does not alter the chemical composition of the substance. Examples include melting, freezing, vaporization, and condensation.
What is changed when matter undergoes a phisical change?
When matter undergoes a physical change, its state may change (solid to liquid, liquid to gas, etc.), its shape or size may change, or its physical properties such as density or volume may be altered. However, the chemical composition of the substance remains the same before and after the physical change.
The expansion of matter upon heating is an example of a?
The expansion of matter upon heating is an example of a thermal expansion, which is the tendency of matter to change in volume, area, and length in response to a change in temperature.
What is a physical change in matter caused by a loss or gain of heat called?
A physical change in matter caused by a loss or gain of heat is called a thermal change.

Matter changes how it looks but not what it's made of?
Physical changes in matter, such as changes in shape or phase, alter its appearance without changing its chemical composition. This means that the substance remains the same at the molecular level even though it may look different. Examples include melting, freezing, and dissolving.
