Yes. But before you write that on your homework, be very sure the question that you asked here is exactly the same as the one your teacher asked on your homework; I suspect it may not be.
Yes, boiling water in a pot on a stove creates water vapor. As the water boils, it transitions from liquid to gas form, producing steam or water vapor.
It depends, which chemical are you trying to find the boiling point for? The boiling point of water is 100 degrees Celsius. For any other chemical, if you have the boiling point in Fahrenheit, just use an online converter.
To increase the temperature of boiling water, you can apply more heat to the water by turning up the stove or using a higher heat setting. You can also increase the pressure around the water, which will lead to a higher boiling point.
No, the bubbles in boiling water for noodles do not indicate a chemical change. The bubbles are formed due to the physical process of water reaching its boiling point and turning into steam bubbles. This is a physical change, as only the state of the water molecules is changing, not their chemical composition.
When a kettle is boiling you are able to see the chemical reaction, from the stem leaving the kettle.
pan boiling by the water on the stove
When a stove is boiling water, electrical energy from the stove is being transformed into thermal energy as the stove heats the water. The thermal energy then causes the water to boil and turn into steam.
This involves a change of state of the water. Before, during, and after the boiling, it remains water. So, since the substance doesn't change its character, the boiling of water is a physical change.
The heat energy from the stove, which in turn comes from the burning of the chemical energy in the gas that is burning, or from the electrical energy, depending on the type of stove.
Yes, boiling water in a pot on a stove creates water vapor. As the water boils, it transitions from liquid to gas form, producing steam or water vapor.
No, boiling water in a kettle on a stove is an example of conduction - the heat from the stove directly transfers to the kettle, heating the water inside.

It depends on what is boiling. If you are boiling WATER, then it is NOT a chemical change, it is a physical change (change of state from liquid to gas). If you are cooking food on the stove, a chemical change is occuring. That is, the chemical bonds within the food molecules are actually changing. One way you can tell that it is a chemical change is that you can't "uncook" food, but you can condense steam back into water.
Yes, turn the heat off. Boiling water does not change its molecular structure, so, yes, it can be "unboiled."
If you turn down the heat of the stove, the temperature of the boiling water will decrease. This is because the heat source is providing less energy to the water, causing it to cool down slightly.
During boiling the chemical composition is not changed.
There could be several reasons why your water isn't boiling. It may be due to low heat, impurities in the water, high altitude, or a malfunctioning stove. Check the heat level, use clean water, consider the altitude, and ensure your stove is working properly.
