Is it a chemical change when the sun melts a cryon?
No, melting is a physical change, not a chemical change. When the sun heats up and melts a crayon, it changes from a solid to a liquid state, but the chemical composition of the crayon remains the same.
What is the chemical change of exposing ice in the sun?
Melting is a physical process.
Is a grape drying in the sun a chemical or physical change?
It is a chemical change. Fermentation causes bonds to break within a compound and new bonds form thus chemically changing the initial 'reactant'.
Is sunburn a chemical change?
No, sunburn is a physical change rather than a chemical change. It involves damage to the skin from overexposure to ultraviolet radiation from the sun, rather than a change in the chemical composition of the skin.
Is getting a sun burn a chemical change or a physical change?
"sunburn" results from physical damage caused to your skin by overexposure to Ultraviolet emissions, usually from the sun but it can also come from a UV lamp. UV light affects damage to the DNA of your skin cells. In defense those cells will produce melanin, a chemical response to try to repair this damage, which also darkens the color of the skin ( a "sun tan").

When a chocolate bar melts in the sun a physical or chemical change?
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.
Is global warming a physical or chemical change?
Global warming is primarily a physical change, as it is the result of the Earth's atmosphere trapping heat from the sun due to increased concentrations of greenhouse gases. However, the increase in greenhouse gases, such as carbon dioxide, is driven by human activities like burning fossil fuels, which involves chemical processes.
Is it a chemical change when the sun melts a cryon?
No, melting is a physical change, not a chemical change. When the sun heats up and melts a crayon, it changes from a solid to a liquid state, but the chemical composition of the crayon remains the same.
Is a crayon melting in the sun a physical or chemical?
Physical. It is still crayon, and the change can be undone by cooling it until it hardens.
What is the chemical change of exposing ice in the sun?
Melting is a physical process.
When sun dries the laundry is it physical or chemical change?
It is both physical and chemical. Evaporation of water is a physical process, and reduction of water from clothing is also a chemical process.
Is the crayon melting in the sun is physical or chemical change?
The crayon melting in the sun is a physical change because only its state changes from solid to liquid without forming any new substances.
Is a grape drying in the sun a chemical or physical change?
It is a chemical change. Fermentation causes bonds to break within a compound and new bonds form thus chemically changing the initial 'reactant'.
Plants changing carbon dioxide and water into sugar and oxygen a physical or chemical change?
Yes it is chemical because the sun is producing food by causing chemicals and substances
