The only changes of state in pure boiling water is from liquid to gas.
It depends on the size of the kettle.
No, a change of state is not a chemical change, for it can be changed back to its original form and their is no change in the molecular composition of the substance. A chemical change is when it cannot be changed back. The above example is an example of a physical change. Example:- ice when heated changes into water and water when cooled changes into ice.
The steam condenses to form water droplets on the cooler surface.
they heat up water in your kettle
The salt dissolves in the water and the sand does not.
When a kettle is boiling you are able to see the chemical reaction, from the stem leaving the kettle.
When a kettle is boiled, it is not a chemical change because the water molecules are simply changing state from liquid to gas due to the heat, without any change in their chemical composition. The process is reversible, as the water vapor can condense back into liquid water.
This process is evaporation.
Liquid to gas
Boiling a kettle is a physical change because it is a change in state from liquid to gas without altering the chemical composition of the water. The water molecules are simply being heated to a point where they gain enough energy to overcome the intermolecular forces holding them together, turning into steam.
Yep. The very definition of 'condensation' is a state change from a gas to a liquid.
No. the hissing and steaming is simply the Physical Change of water boiling, and the steam causes an increase in pressure thus the whistle. During a Physical Change, some properties of material change, but the composition of the material does not change.
Heat transfer in a kettle occurs through conduction. The heat from the stove is transferred to the bottom of the kettle, which then spreads throughout the kettle via conduction, causing the water inside to heat up. Heat is also transferred through convection as the hot water rises and circulates within the kettle.
The property illustrated by boiling water in a kettle is a change in state from liquid to gas. As the water is heated, it gains enough energy to overcome the attractive forces holding its molecules together, causing them to break free and turn into vapor.
The change of state that occurs when a puddle disappears is evaporation. The liquid water in the puddle turns into water vapor and escapes into the air.
The formation of steam from boiling water in a kettle is a physical change. It involves a phase change from liquid to gas without altering the chemical composition of the water molecules.
It is a 'State' Change called Liquification, precipitation and other terms depending on the process that caused the state change.
