The warmer water cannot rise; instead it remains near the heat source, getting hotter and hotter. Meanwhile, the remaining water further away from the heat source stays relatively cool. As the heated fluid reaches its boiling point, the bubbles do not rise to the surface.
What will happen to the water if you continue heating it?
When water is heated, it evaporates. The molecules move and vibrate so quickly that they escape into the atmosphere as molecules of water vapor.
What happens when we heat a liquid until it boils?
As a liquid is heated, its vapor pressure increases until the vapor pressure equals the pressure of the gas above it. … In order to form vapor, the molecules of the liquid must overcome the forces of attraction between them. The temperature of a boiling liquid remains constant, even when more heat is added.
What do you think would happen to the temperature of the water if heating at the boiling point continued for an additional 5 minutes?
The water changes state, liquid to vapor, as energy is added. The vapor can be the same temperature as the water, or higher or lower. But the liquid water remains the same temperature in its boiling condition. The temperature remains the same.
What happen the water before heating?
When heat is first applied to water, it must break the intermolecular hydrogen bonds within the sample. After breaking the bonds, heat is then absorbed and converted to increased kinetic energy of the molecules in order to vaporize them.
What happens when water is heated quizlet?
As molecular motion increases, the space between molecules increases . As molecular motion decreases, the space between molecules decreases. What happens when you heat a liquid? When heat is added to water the molecules in the liquid speed up and move further apart from one another.
What happens when a liquid boils?
Boiling. If a liquid is heated the particles are given more energy and move faster and faster expanding the liquid. … Eventually even particles in the middle of the liquid form bubbles of gas in the liquid. At this point the liquid is boiling and turning to gas.
At what temperature water will boil?
At sea level, water boils at 100° C (212° F). At higher altitudes the temperature of the boiling point is lower. See also vaporization.
What happens if you heat lead?
Lead fumes are produced during metal processing, when metal is being heated or soldered. Lead dust is produced when metal is being cut or when lead paint is sanded or removed with a heat gun. Lead fumes and lead dust do not have an odor, so you may not know you are being exposed.
