What is The process in which water in liquid form on the surface is heated and changed to vapor form?
the simple answer is boiling. when the vapor pressure of the liquid matches or exceeds the pressure on the liquid it will turn to vapor. a pot of water on a stove at sea level will boil,or vaporize, when the vapor pressure meets or exceed 14.7 psi, or atmospheric pressure. this as we know is reached at 212 degrees F, or 100 deg C. as the pot is elevated the temperature to boil is reduced due to the reduced atmospheric pressure at a given elevation. a typical lab experiment hooks a vacuum pump up to a container of water, and at some level of vacuum the water will boil, or vaporize, with no increase in temperature required; only by decreasing the pressure on the liquid to the vapor pressure.

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.
Does water changes from a liquid to a gas in the process of evaporation.?
Yes, evaporation is the process by which a liquid, like water, changes into a gas when heated. It occurs when molecules on the surface of the liquid gain enough energy to break free from the liquid's surface and become vapor in the air.
What happens if a molecule with a high kinetic energy happenes to be close to the liquid's surface?
Then that molecule will escape the surface of the liquid and become a molecule of gas. This is the process by which water slowly evaporates even when not heated.
What is the process that every time a liquid turns into a gas it undergoes this process?
Boiling - when the liquid is heated to a gas. Evaporating - when the air temperature is hotter than the surface of the liquid so the water turns into water vapor or a gas.
Can salt be changed from solid to liquid or from liquid to gas?
Salt can be changed from solid to liquid by heating it to its melting point, which is 801°C. Once it reaches this temperature, it will turn into a liquid. However, salt cannot be changed directly from liquid to gas through a process like evaporation; instead, it will first need to be heated to a very high temperature to turn it into a gas.
What is heated liquid turned to gas called?
Evaporation is the process and the gas formed by liquid in heated condition is called vapours
What happens to the surface tension of a liquid when it is heated?
As a liquid is heated, its surface tension typically decreases. This is because the increased thermal energy disrupts the intermolecular forces at the surface of the liquid, causing the molecules to spread out and reducing the cohesive forces that create surface tension.
Liquid water is heated. it changes from a liquid to a?
When liquid water is heated it changes from a liquid to a gas and then, usually, to a vapor.steam comes to mind
The continuous process by which water moves from Earth's surface to the atmosphere is called what?
The continuous process by which water moves from Earth's surface to the atmosphere is called evaporation. This occurs when water is heated by the Sun and changes from liquid to vapor, rising into the atmosphere.
When a liquid is heated and turns into water vapors?
This process is known as evaporation. As the liquid absorbs heat energy, the molecules gain enough kinetic energy to escape the liquid's surface and become water vapors. Evaporation is a phase transition from liquid to gas that occurs below the boiling point of the liquid.
What is the name of the process were a liquid is heated and becomes a gas?
a cat
