When a chocolate bar melts in the sun, it is a physical change. This is because the chocolate undergoes a phase change from a solid to a liquid without changing its chemical composition.
Examples of evaporation include a wet towel drying in the sun, a puddle of water disappearing on a hot day, and the process of water turning into steam when heated in a kettle.
A crayon melting in the sun is a physical change. The crayon is undergoing a phase change from solid to liquid due to the heat from the sun. No new substances are being formed during this process.
The sidewalk being warmed by the heat of the sun is a physical process. The sun's rays transfer heat energy to the sidewalk through radiation, causing the molecules in the sidewalk to vibrate more rapidly and increase in temperature. This is a physical change as no new substances are being formed in this process.
The crayon melting in the sun is a physical change because only its state changes from solid to liquid without forming any new substances.
Drying (involving only the water evaporation) is a physical change.
A grape drying in the sun is a physical change. The process involves the removal of water from the grape due to heat, but the chemical composition of the grape does not change.
The evaporation of water from a puddle in the sun is a physical change, as only the state of the water is changing from liquid to gas without any new substances being formed.
what are the example of sun and air drying
Drying soil samples under the sun can lead to uneven drying, which can affect the accuracy of test results. The sun's heat can also alter the soil's chemical and physical properties. Controlled drying methods, such as using an oven or air-drying in a shaded area, are preferred to ensure consistent and reliable results.

No. It is a nuclear change.
A crayon melting in the sun is a physical change. The crayon is undergoing a phase change from solid to liquid due to the heat from the sun. No new substances are being formed during this process.
Warming up in the sun is a physical change. It involves an increase in temperature causing molecules to move faster and spread out, but no new substances are formed.
Light from the Sun provides life.
