Is there evidence of a chemical reaction when bubbles form on heated water?
Bubbles forming on heated water are usually due to the process of water vaporization rather than a chemical reaction. When water is heated, the molecules gain energy and move faster, eventually reaching a point where they break free from the liquid surface and form bubbles of water vapor. This phase change is a physical process, not a chemical reaction.
What is a mass of small bubbles on a liquid called?
A mass of small bubbles on a liquid is called foam. Foam is formed when air gets trapped in liquid, creating a bubbly mixture at the surface.
What is the temperature at which a liquid forms bubbles of vapor that break at the surface?
Boiling Point
When a liquid boils do bubbles form throughout the liquid?
yes it would because when the liquid boils the entire container of liquid is heated to the boiling point, meaning that the liquid would turn to the vapor form all around the liquid.
How a cold drink bubbles?
When a cold drink is opened, carbon dioxide gas that is dissolved in the liquid is released in the form of bubbles. The lower temperature of the drink prevents the gas from escaping quickly and allows more bubbles to form, resulting in the fizzy or bubbly sensation.
What is it called when bubbles escape the surface of a heated liquid?
The process of bubbles escaping the surface of a heated liquid is called boiling. It happens when the liquid reaches its boiling point and the vapor pressure equals the atmospheric pressure, causing bubbles to form and rise to the surface.
When heated bubbles rise to surface?
bubbles rise to the surface of a heated liquid as it changes to gas because they are less dense than the liquid.
Why do vapor bubbles rise to surface when a liquid is boiling?
Vapor bubbles rise to the surface during boiling because the liquid is being heated, causing the molecules to gain energy and form gas bubbles. These bubbles are lighter than the surrounding liquid and therefore float to the surface. The bubbles burst at the surface, releasing the gas into the air.
Why does the liquids rate of evaporation increase when the liquid is heated?
Heating a liquid increases the kinetic energy of its molecules, causing them to move faster. This increased movement at the liquid's surface leads to more molecules escaping into the air as vapor, thus increasing the rate of evaporation.
How do bubbles form in boiling water?
When water boils, the heat converts some of the water to steam and each bubble is a steam bubble. Steam is a gas that is lighter than water, and so the bubbles rise to the surface of the water where the steam is released. As the steam cools in the air, it forms water vapor, and that is what we see. Most people call the vapor "steam", but steam is a transparent gas, like air.
What forms bubbles surface tension?
Bubbles are formed due to a combination of surface tension and gas trapped in a liquid. The surface tension of the liquid causes the bubble to retain its spherical shape. When a gas is introduced into the liquid, the surface tension pulls the liquid molecules together around the gas to form the bubble.
What has the liquid reached when a liquid forms gas bubbles below its surface?
its still liquid but its starting to form into gas

Why does water bubble when you boil it?
Boiling converts the liquid water to water vapor. The bubbles are the water vapor escaping. As substances warm up, they become less dense, and the less dense something is, the less mass it has, so the water vapour rises to the top. Water in a pan or kettle bubbles like this because the source of heat is at the bottom, so the water near the bottom boils first. If you could somehow heat something from the top down, it probably wouldn't bubble.Water vapor is formed at the heated surface, and tends to coalesce on nucleation sites like an inflating balloon until it is carried to the free surface and released.
