A frozen pipe is a physical change, as it is just water changing state from liquid to solid (ice).
However, a rusted metal bike is a chemical reaction as it is caused by the metal reacting with the oxygen in the air, in what is called an oxidation reaction.
Metal can quickly rust when it is exposed to water and oxygen, which causes a chemical reaction that forms rust on the surface of the metal.
Yes, rusted pots and pans are a result of a chemical change. This occurs when the metal reacts with oxygen and water to form iron oxide (rust), which is a different substance than the original metal.
The metal chair is likely to undergo corrosion, where the metal will react with oxygen and water from the air and rain, leading to the formation of rust (iron oxide) on its surface. This process weakens the metal structure over time.
When a metal molecule releases energy, it is undergoing a process called exothermic reaction. This means that the molecule is releasing heat or light energy as it undergoes a chemical change.
Burning a candle or causing oxidation of a chemical. You can also create heat by placing sodium metal in water (caution, this is dangerous).
Metal can quickly rust when it is exposed to water and oxygen, which causes a chemical reaction that forms rust on the surface of the metal.
Yes, rusted pots and pans are a result of a chemical change. This occurs when the metal reacts with oxygen and water to form iron oxide (rust), which is a different substance than the original metal.
Yes but with poor results. How about cutting the rusted metal out and replacing it?
you use chemical energy by cooking an egg, burning wood, water on wood/metal
yes
yes
To achieve a rusted look on galvanized metal, you can use a combination of vinegar, hydrogen peroxide, and salt to create a rusting solution. Apply the solution to the metal and let it sit for a few hours or overnight to develop the desired rusted effect.
Metal can be rusted through a process called oxidation, which occurs when the metal comes into contact with oxygen and moisture in the air. This causes the metal to corrode and form rust, even without the use of hydrogen peroxide.
A sparkler has chemical energy stored in the compounds of the metal fuel and oxidizer mixture. When ignited, this chemical energy is converted into thermal energy (light and heat), resulting in the glowing and sparking effect of the sparkler.
The metal chair is likely to undergo corrosion, where the metal will react with oxygen and water from the air and rain, leading to the formation of rust (iron oxide) on its surface. This process weakens the metal structure over time.
Yes, it is a form of the verb "to rust" (oxidize, crumble). It is the past tense and past participle,and can be used as an adjective (rusted metal).
When a metal molecule releases energy, it is undergoing a process called exothermic reaction. This means that the molecule is releasing heat or light energy as it undergoes a chemical change.
