Melting is a physical change.
Yea Photosynthesis is the chemical change in plants that uses the sun's energy and converts it into glucose and oxygen.
It is a chemical change. Fermentation causes bonds to break within a compound and new bonds form thus chemically changing the initial 'reactant'.
Photosynthesis is the chemical change of the suns energy into glucose and oxygen.
It is a chemical change, because the sun converts hydrogen into helium to create heat and light.
It melts into liquid (water)
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.
Physical because on the appearance of the chocolate bar changed
Physical, Since only the property of the chocolate didn't change, after it melted, it still is chocolate
It melts it.
When the sun melts a crayon, a physical change occurs because the crayon changes from a solid to a liquid state without undergoing any chemical reactions. The crayon can be cooled down again to solidify and return to its original state.
No. It is a nuclear change.
Yes, yellowing of newspapers in the sun is a chemical change. The exposure to sunlight causes a chemical reaction in the paper fibers, breaking down the cellulose molecules and leading to a change in color.
When a chocolate bar melts in the sun, it is a physical change. This is because melting is a reversible process in which the chocolate changes from a solid to a liquid state due to the increase in temperature. No new substances are formed during this process, making it a physical change rather than a chemical change.

This chemical reaction is called photosynthesis.
