Why does metal change color when heated?
When metal is heated, its atoms vibrate more rapidly and absorb energy. This causes the electrons in the metal to move to higher energy levels, which can change the way they interact with light. This change in electron behavior can result in the metal appearing to change color as different wavelengths of light are reflected.
When crushing an aluminum can has it undergone a physical or chemical change?
Crushing an aluminum can is a physical change because the substance itself (aluminum) remains the same before and after crushing. The change in shape and size does not alter the chemical composition of the can.
Change in state when sulphur is heated?
When sulfur is heated, it undergoes a phase change from solid to liquid, and then from liquid to gas due to sublimation. Sulphur does not undergo a direct change from solid to gas.
Is aluminum wrapped around an apple a physical change?
Yes, wrapping aluminum around an apple is a physical change because it does not alter the chemical composition of either the aluminum or the apple. It is simply a change in the physical state or appearance of the objects involved.
What state of matter does aluminum naturally exist in?
Aluminum naturally exists in the solid state at room temperature and pressure. It has a high melting point (660.3°C) and therefore remains solid unless heated to that temperature.
Does talc change color if heated?
Talc don't change the color if heated.
Can you make aluminum foil change colors?
Yes, it is possible to change the color of aluminum foil by applying heat to it. When heated, the oxide layer on the surface of the aluminum can change color based on the temperature, creating a rainbow effect. However, prolonged exposure to high temperatures can cause the foil to deteriorate.
Why does an change color and texture when heated?

What color does aluminium turn when heated?
When heated, aluminum typically turns a dull gray color due to the formation of an oxide layer on its surface. This oxide layer acts as a protective barrier to prevent further corrosion.
What is the chemical formula for aluminum oxide when heated?
Aluminum oxide is Al2O3 and when heated it is still Al2O3, so heating aluminum oxide does nothing to it.
Why does a egg change color when heated biology?
The parts of the egg (proteins) have become denatured when heated (cooked).
What is the color change when hydrated ferrous sulphate is heated?
When hydrated ferrous sulfate is heated, it loses its water molecules and undergoes thermal decomposition. The color change is from pale green (hydrated) to white (anhydrous).
Why green color of feso4 changes when heated?
The green color of FeSO4 changes when heated because it undergoes a dehydration reaction. Heating causes the water molecules in the compound to be removed, leading to a change in the oxidation state of iron from +2 to +3, resulting in a color change.
What color does barium chloride become when heated?
Barium chloride is white in its solid form. When heated, it remains white because its color does not change.
