Do molecules rise or sink after they are heated?
When molecules are heated, they increase in kinetic energy and tend to rise due to decreased density. This is because as a substance is heated, its molecules spread out and become less dense, causing them to rise in a fluid medium such as air or water.
What happens because water vapor molecules are lighter than nitrogen or oxygen molecules?
Water vapor molecules rise in the atmosphere, causing them to form clouds and ultimately precipitation. This is because lighter molecules have more kinetic energy and therefore move faster, allowing them to rise above the heavier nitrogen and oxygen molecules.
Why does soap makes bubble?
soaps,shampoos,shaving creams contain sodium laryl sulphate or sodium laureth sulphate which produces foam when used.this also causes cancer it is a carcinogen .this causes cancer.eventhough they are using it in their products since it gives foam
Why does the boiling point of water rise if salt is present?
The salt reduces the number of water molecules from escaping the surface into the air. Thus, the water has to be at a higher temperature to be able to push the salt molecules aside and finally reach the surface and evaporate.
What change in the water level occurs when you hold Erlenmeyer flask over a candle in a pan of water?
When you hold an Erlenmeyer flask over a candle in a pan of water, the water inside the flask heats up and expands, causing the water level in the flask to rise. This is due to the expansion of the water molecules as they gain thermal energy from the heat source.
What property of water gives rise to capillary action?
The property of water that gives rise to capillary action is adhesion, which is the attraction between water molecules and the molecules of the material making up the capillary tube. This leads to water being pulled up the tube, against the force of gravity, due to the cohesive forces between water molecules.
Describe the biological significance of the cohesiveness of water?
Well, one really big and well known reason is that it allows water to be transported through plants. The sun exaporates water and cohesion allows the water to be sucked up to the leaves from the bottom even with gravity pulling down on it because of the constantly reformed hydrogen bonds.
Why level of water does not rise when sugar crystal dissolves in water?
it is so because the sugar molecules get accomodated between water molecules ....such spacing is also called as intermolecularspaces....hence level of water does not increases...
What is the tendency of water molecules to stick to molecules of another substance?
The tendency of water molecules to stick to molecules of another substance is known as adhesion. Water molecules have a strong attraction to other molecules due to their polarity, forming hydrogen bonds with the molecules of a different substance. This adhesion property of water allows it to interact with and dissolve a wide variety of substances.
How does water rise to the top of a redwood tree?
adhesion of water to the wood and cohesion of water molecules
Do molecules rise or sink after they are heated?
When molecules are heated, they increase in kinetic energy and tend to rise due to decreased density. This is because as a substance is heated, its molecules spread out and become less dense, causing them to rise in a fluid medium such as air or water.
Why is a balloon more buoyant on a hot day?
the heat gives the molecules more energy to move around and rise.
Are water molecules in a cloud?
Yes, clouds are formed from water molecules that have evaporated from bodies of water on Earth. These molecules rise into the atmosphere and cool down, forming tiny liquid water droplets or ice crystals that make up a cloud.
How does water move in evaporation?
Water molecules at the surface of a body of water gain enough energy from the environment to break free from the liquid phase and become water vapor. These water vapor molecules rise into the atmosphere, contributing to evaporation.
What happens because water vapor molecules are lighter than nitrogen or oxygen molecules?
Water vapor molecules rise in the atmosphere, causing them to form clouds and ultimately precipitation. This is because lighter molecules have more kinetic energy and therefore move faster, allowing them to rise above the heavier nitrogen and oxygen molecules.

Why does water vapor rise when liquid water is heated by the sun?
By heating the intermolecular forces are weakened and liquid molecules can escape as a gas.
