Water is a simple molecule made up of two hydrogen atoms and one oxygen atom. When water is heated, the molecules move faster and have more energy. Eventually, the water molecules will have enough energy to break apart from each other and turn into steam.
This change from liquid water to steam is called boiling, and it is a physical change.
In order to answer this question, we must first understand what a chemical change is. A chemical change is a permanent change in the composition of a substance. This means that the molecules of the substance are rearranged and new molecules are formed.
With that said, water heated and changed to steam is definitely a chemical change. When water is heated, its molecules break apart and reform into new arrangements. These new arrangements result in the formation of steam – which has different properties than water.
1) What is Water Heated And Changed to Steam
Water is a substance that is made up of two elements, hydrogen and oxygen. When these two elements are combined, they form H2O, or water. Water can exist in three different states: solid (ice), liquid (water), and gas (steam).
When water is heated, the molecules begin to move faster and further apart. Eventually, the molecules have enough energy to break free from the attractions holding them together in a liquid state. When this happens, the water turns into a gas called steam.
The boiling point of water is 212 degrees Fahrenheit (100 degrees Celsius). This means that when water is heated to this temperature, it will turn into steam. However, steam can exist at much higher temperatures than this.
For example, if you put a pot of boiling water on the stove and then turned off the heat, the water would eventually cool down and turn back into a liquid. But if you left the pot on the stove with the lid off, all of the water would eventually evaporate and turn into steam. Steam is often used to power turbines which then generate electricity.
This process is called thermal power generation or simply “steam power”. In order for this to happen though, extremely high temperatures are necessary – around 1000 degrees Celsius! Fortunately, we have access to materials that can withstand these kinds of temperatures like metals such as steel.
Changing water- States of matter
Water is Heated And Changed to Steam is That a Physical Or a Chemical
When water is heated, the molecules begin to move faster and collide with each other more frequently. This causes the water to expand and change into steam. The change from liquid water to steam is a physical change, since no new substances are formed during this process.
Iron Rusting is a Chemical Change
Iron rusting is a chemical change because it involves a chemical reaction between the iron and the oxygen in the air. The iron reacts with the oxygen to form iron oxide, which is also known as rust. The rust helps to protect the iron from further corrosion.
Is Baking Soda Reacting to Vinegar a Chemical Change
When vinegar and baking soda are mixed together, they create a foamy reaction. This is because the two substances are chemically reacting to each other. The carbon dioxide gas that is produced during this reaction is what makes the mixture foamy.
The chemical reaction between vinegar and baking soda can be used as a cleaning agent. When the two substances are mixed together, they produce a mildly abrasive cleaning solution that can be used to clean surfaces in your home.
Potassium Chlorate Decomposes to Potassium Chloride And Oxygen Gas Physical Or Chemical Change
When potassium chlorate decomposes, it changes from a salt to a metal chloride and oxygen gas. This is definitely a chemical change! The reason why this is a chemical change and not just physical is because when the molecules of potassium chlorate break apart, they create new molecules of potassium chloride and oxygen gas.
These are completely different molecules than before the decomposition reaction took place.
When water is heated, the molecules gain energy and begin to move faster. As they move faster, they collide with other water molecules and break apart the hydrogen bonds that hold them together. When enough bonds are broken, the water molecules turn into steam and rise into the air.
This process is called vaporization and it is a physical change because the water molecules have simply changed their state from liquid to gas. However, when water molecules are turned into steam, they form new bonds with each other and create entirely new molecule structures. This process of breaking old bonds and forming new ones is called a chemical change.
