What happens to molecules when water is boiled?

Answer 1

By increasing the air pressure above the water (apex)

Answer 2

When water is boiled, the molecules gain enough kinetic energy to overcome intermolecular forces holding them together, causing the water to transition from a liquid to a gaseous state (vapor). This phase change is due to the increased temperature breaking the hydrogen bonds between water molecules, allowing them to escape as steam.

Answer 3

The continuous addition of thermal energy (heat) gives more and more kinetic energy to the water molecules. Eventually the molecules have so much kinetic energy that they break the bonds holding the molecules in liquid form and escape into the air in the phase change to a gas.

Answer 4

When water molecules are boiled, they increase in energy and vibrational speed. Eventually, their vibrations are enough to break the intermolecular bonds holding them together. When this happens, the water molecules escape the liquid form and turn into vapor.

Answer 5

The addition of heat is increasing the temperature, which is the average kinetic energy of the molecules. If the kinetic energy of the molecules is increasing, then they are moving faster. Eventually, these molecules move fast enough that they can "unstick" from their hydrogen bonds. Then the molecules are free to float as a gas.

Answer 6

A liquid boils when its vapour pressure becomes equal to the external pressure. Adding a salt generally increases the b.p. This is because the presence of the solute decreases the vapour pressure of the solution. Increasing the external pressure also raises the boiling point of a liquid. In both cases we now have to supply more energy to make the liquid's vapour pressure equal the external pressure.

Answer 7

You can either boil it or heat it up.

In terms of molecues, the temperature increases when the molecues or atoms start moving faster, generating heat, which slowly increases the temperature of the water.

Answer 8

You can greatly increase the boiling point of water by boiling it in a pressure cooker, although that may not be what you had in mind. Pressure cookers do work at sea level, but they create pressure that is higher than the normal air pressure at sea level. You can also increase the boiling point of water by adding salt. Just as salt lowers the freezing point, it also raises the boiling point. Not as much as a pressure cooker, though.

Answer 9

By adding a solute or by increase of pressure.

Answer 10

they rise up and as the water rises the water get more shallow and it gets closer to the gas or electric
