stays the same
During a physical change, the substance's form or state may alter, but its chemical composition remains the same. This means no new substances are formed, and the change is usually reversible by physical means such as heating, cooling, or mixing with other substances. Examples include melting, freezing, boiling, or dissolving.
Some indicators of a chemical reaction are: - change of color - change of odor - release of a gas - change of the temperature - change of the viscosity - formation of a precipitate - change of general appearance - possible explosion - possible chemiluminiscence
During a chemical change, matter is rearranged to produce new forms of matter. This is a result of either the sharing or transfer of electrons between different atoms. Observable evidence of a chemical change can be, but is not limited to, the formation of bubbles, a change in color or temperature, and the presence of a smell.
During a phase change, the temperature remains constant even though heat is being added to the system. This is because the energy is being used to break intermolecular forces rather than increase the temperature of the substance. Once the phase change is complete, the temperature will start to rise again.
During a physical change, the composition of matter remains the same. The atoms and molecules of the substance do not change; only the arrangement or state of the matter is altered. This means that no new substances are formed during a physical change.
Temperature remains constant
nothing
The temperature remain constant during a change of phase.
The temperature* remains unchanged. * The heat (energy) content changes.
During a phase change, the temperature remains constant as the substance absorbs or releases heat energy to change from one phase to another. This is because the energy is used to break or form intermolecular bonds rather than raise or lower the temperature.
Nothing happens to the temperature during a lunar eclipse. Nothing ishappening on Earth during a lunar eclipse. It's the moon that's goingthrough the Earth's shadow and becoming dimmer.(But I'll bet you the temperature on the moon sure changes when that happens.)
Temperature remains constant during the change in phase (physical state).
During no temperature change, the ice remains in a solid state. The molecules of the ice stay tightly packed together in a regular pattern, maintaining its structure. While there may not be a change in temperature, other factors such as pressure or surrounding conditions can affect the state of the ice.

During a chemical reaction, properties that can change include color, temperature, state of matter (solid, liquid, gas), odor, and the formation of new substances with different chemical properties.
A physical change involves a transformation in the appearance, shape, or state of a substance, while its chemical composition remains the same. This means that no new substances are formed during a physical change.
