Put a lid on it. If you block evaporation, using a pressurized container (one that the lid locks onto) it IS possible to raise the temperature of the water beyond the boiling point.
BE VERY CAREFUL!!! There needs to be a pressure relief device. Accumulating steam can cause a tightly sealed system to violently explode. Ask your gram about the old style pressure cookers. She may still have one.
Another possibility is to use pure distilled water in a very smooth container. Boiling requires the presence of nucleation sites--some form of impurity or disturbance on which bubbles of water vapor can form. Remove the nucleation sites by using distilled water in a very smooth container, and you create the conditions for a condition known as superheating. This is where water continues to absorb heat even though it's past its evaporation point because it has no way to transition into vapor. You must be very careful in this scenario as well! The slightest disturbance in the water will cause it to react violently!
If it is not necessary to boil just water, one of the more common ways to raise the boiling point of water is to dissolve something in it: usually salt. It's a common technique of canning and cooking because raising the boiling point raises the cooking temperature, making it more effective. This is why some recipes (like for cooking pasta) suggest you add salt to the water while it's heating. It's not just for taste.

What boils at what degree Celsius?
This question is too vague to answer: many different substances boil at many different degrees Celsius. In fact the same substance can be made to boil at different temperatures by changing the pressure acting on it.
When do water molecules have the most greatest amount of energy?
Steam at 100C
How boiling is done successfully?
To boil water successfully, place a pot of water on the stove over high heat. Wait for the water to come to a rolling boil, where bubbles are rapidly rising to the surface and breaking. Once boiling, reduce the heat to maintain a gentle boil as needed for your recipe.
Will salt water boil or will regular water boil?
Both salt water and regular water will boil. However, salt water will have a higher boiling point than regular water due to the presence of salt in the solution.
When does liquid change to vapor?
it depends what the liquid is. water liquid turns into vapour at 100c
What temperateure does water boil?
212F or 100C
What is the state of water at 257c?
There isn´t water at 257c because the water was starting to boil and to evaporate at 100c.
What temperature in degress celsius does water freeze and boil?
it freezes at 0C and boils at 100C
Why water mixed with sugar doesn't evaporate at 100c?
the sugar solution will not boil at 100C because the solute(sugar) has a slight attraction on the water molecules, increasing the boiling point and lowering the freezing point.
Will water boil at 100C at the top of a mountain?
no because at the top of the mountain its less pressure than at the sea level so it will take more time to boil
When will water boil at temperatures less than 100C?
When the gas phase pressure is less than 1 atmosphere.
Mount everest has a high pressure to boil water?
The boiling point of water changes with altitude. While it boils at 100C at sea level, at the summit of Mount Everest water would boil at a lower temperature of 72C.
Can water boil at 95C or 105C?
Yes - it depends on the height above or below sea level; so not always 100C as expected.
Why does water not boil at 100 degrees celsius in Atlanta GA?
100C is at sea level. Water boils at different temperatures based on the altitude you are at. Atlanta is 738 to 1050 feet in elevation. In Denver Co. at 5,280 feet you will find it boils at far less than 100C.
What boils at what degree Celsius?
This question is too vague to answer: many different substances boil at many different degrees Celsius. In fact the same substance can be made to boil at different temperatures by changing the pressure acting on it.
What is boiling point if mount Everest and normal water?
The boiling point of water changes with altitude. While it boils at 100C at sea level, at the summit of Mount Everest water would boil at a lower temperature of 72C.
What temperature does water boil at in Kelvin?
It boils at 373 degrees kelvin. Kelvin is just Celsius plus 273. Water boils at 100C, 100+273=373, so 373K.
