Why steam condensing is physical change?

Steam condensing is considered a physical change because it involves a change in the state of matter (from gas to liquid) without a change in the chemical composition of the substance. The molecules in the steam lose energy and come closer together to form liquid water, but they remain the same H2O molecules.


How much heat must be removed from steam to change it to a liquid?

The amount of heat that must be removed from steam to change it to a liquid is the latent heat of vaporization of water, which is approximately 2260 kJ/kg at atmospheric pressure. This is the amount of energy required for water to change from a gas to a liquid state at a constant temperature.


Is boiling water to make steam a physical change?

Yes, boiling water to make steam is a physical change. This is because the water undergoes a change in state from liquid to gas without any change in its chemical composition.


Do the particles in steam have very low density?

The particles them self, assuming that you are referring to the individual atoms/molecules that makes up a liquid, does not change in "density" when going from one state of matter to another (liquid -> steam). However, the density changes for a certain amount of the matter, for instance one liter. One liter of water weighs a lot more than one liter of water steam. This is because the density of liquid water is much higher than water steam. The density of liquid water is 1000g/liter while the density of steam is 0.8g/liter. In other words, liquid water is over 1200 times denser than water vapor!


Are air water and steam all liquids?

Air is primarily composed of gases like nitrogen, oxygen, and carbon dioxide, so it is not a liquid. Water can exist in three states: solid (ice), liquid (water), and gas (steam). Steam is the gaseous form of water, not a liquid.

When water changes to steam it undergoes a chemical change true or false?

False. When water changes to steam, it undergoes a physical change, not a chemical change. Heating water to its boiling point causes it to change from a liquid to a gas, but the chemical composition of water (H2O) remains the same.


Why liquid water changing into steam is a physical not a chemical change?

The steam when cooled changes back to liquid water. A chemical change is usually not so reversible.


Is production of steam a chemical or physical change?

The change from liquid water to steam is a physical change in the state of matter. Evaporation is the term for a liquid becoming a gas.


Water changing to steam is an example of what kind of change?

Water changing to steam is an example of a physical change, specifically a phase change from liquid to gas. This change is reversible as the steam can condense back into water under certain conditions.


How can you change a liquid to a vapor?

boil it ! steam is vapourised water.


Is steam a chemical raection?

No. Steam is water vapor. Steam is formed by boiling water, which is a physical change.


A state change is an example of what?

An example of a change of state is an ice cube melting and becoming liquid water, or liquid water boiling to become steam.


Is steam turning to water a chemical or physical change?

The formation of steam is a physical change. The chemical composition of steam (water vapor), is H2O, and the chemical composition of liquid water is H2O, so there is no chemical change going from liquid to gas (vapor/steam). Thus, it is a physical change.


When water changes to steam is it a chemical change?

The change of water to steam is a physical change, not a chemical change. In this case, the water molecules are simply changing phase from a liquid to a gas, but the chemical composition of water remains the same.


The process of steam condensing to form liquid water is?

The process of steam condensing to form liquid water involves the transfer of heat energy from the steam to the surrounding cooler environment. As the steam loses heat, its temperature decreases and it undergoes a phase change from gas to liquid. This results in the formation of liquid water droplets.


WHAT DO YOU CALL THE CHANGE FROM STEAM OR WATER VAPOR BACK TO LIQUID?

The change from steam or water vapor back to liquid is called condensation. This process occurs when the vapor cools down and turns into liquid droplets due to a decrease in temperature.


The change from water to steam is?

a phase change from liquid to gas that occurs when water is heated to its boiling point. This process requires energy to break intermolecular bonds and cause the water molecules to transition from a liquid state to a gaseous state.
