Why the boiling point of water is 98 in Kaghan?
The boiling point of water decrease when the altitude increase and the atmospheric pressure decrease.
Does salt helps to decrease the boiling point of water?
No
What are two examples of changes in state that will generate an increase in molecular motion?
Melting ice to form liquid water or boiling liquid water to produce steam are two examples of changes in state that lead to an increase in molecular motion. In both cases, the added energy causes the molecules to move more rapidly and with greater freedom.
What is the rolling motion of boiling water an example of?
The rolling motion of boiling water is an example of convection. In this process, hot water rises to the surface as it heats up, while cooler water descends to take its place, creating a circular motion. This movement helps distribute heat evenly throughout the water, facilitating the boiling process. Convection is a key mechanism in fluid dynamics that illustrates how temperature differences can drive motion in liquids and gases.
Does boiling the water separate the H from the O What is in the bubbles?
Boiling water does not separate hydrogen from oxygen; it merely converts water (H₂O) from liquid to gas through the process of vaporization. The bubbles you see in boiling water are primarily water vapor, which is water in its gaseous form. These bubbles form when water reaches its boiling point, causing it to turn into steam. The molecular structure of water remains intact during boiling.

Can you reverse water boiling on the stove?
Yes, turn the heat off. Boiling water does not change its molecular structure, so, yes, it can be "unboiled."
Does boiling water soften substances?
Yes, boiling water can soften substances by breaking down their molecular structure and making them more pliable.
Compare boiling point of water on kelvin and celsius scale?
The boiling point of water is 100 degrees Celsius, which is equivalent to 373.15 Kelvin. The Kelvin scale starts at absolute zero, where there is no molecular motion, while the Celsius scale starts at the freezing point of water.
Occurs when heat is transferred into an object through motion or movement an example would be boiling water.?
Convection occurs when heat is transferred into an object through motion or movement; an example would be boiling water.
What if iodized salt is boiled?
the temperature of boiling water that is mixed with iodized salt will decrease.
How does air expand in hot water?
due to forced convection and molecular motion
How does a boiling water vortex form and what are its characteristics?
A boiling water vortex forms when water is heated to its boiling point and starts to circulate in a swirling motion. This happens because the hot water rises and cooler water moves in to take its place, creating a vortex. The characteristics of a boiling water vortex include a central column of rising steam, a swirling motion of the water, and a relatively stable shape as long as the heat source is maintained.
Why should you use the word average when describing molecular motion?
The term average must be used as the molecular motion is not completely uniform. ie. some of the molecules will vibrate at different frequencies and amplitudes, around a fixed average position. This is shown as water can evaporate even if it is below the boiling point, as some molecules have enough energy to escape. the boiling point is when the average energy is 100 degrees centigrade, so the molecules turn to gas.
