When the water in a pond gets so cold that it hardens on the surface, it is undergoing a change of state from liquid to solid, which is called freezing. This process occurs when the temperature drops to 0 degrees Celsius (32 degrees Fahrenheit) or below, causing the water molecules to slow down and arrange themselves into a solid crystalline structure, forming ice.
It is a physical change from a rough to a smooth surface.
These marshmallows are going through a chemical change. How is this different from a physical change?
Yes, it is faster
You think probable to catalysts.
The change from gas to solid without going through the liquid state is called deposition. This occurs when gas directly transforms into solid form by losing heat energy, bypassing the liquid phase. An example of deposition is frost forming on a surface when water vapor in the air turns directly into ice crystals.

The change of a gas directly to a solid is called deposition. This process skips the liquid state and involves the direct conversion of gas molecules into solid molecules. An example of deposition is frost forming on a cold surface.
Depends where you live. Speak to your doctor
There is no change in the colour of urine during menopause.
It is true that light will change direction when going from one medium to another (such as going through space to going through air. Further, different wavelengths of light (different colors) will change at different angles; this is why a prism works and why the sky is blue. However, this process is called refraction, not reflection.
light reflect and refract while going 4m one to other medium......one can understand it through particle nature of light,,,,,,light is a strem of photons that undergo collisions at the surface of mediums......................
