How does atmospheric pressure affect the boiling point of matter?
Atmospheric pressure exerts pressure on the molecules of the liquid, confining them. In order to boil, the electrons must be excited, but must become hotter to overcome the pressure of the atmosphere. Therefore, pressure makes a liquid boil at a higher temperature. With a solid, the molecules are already compact together and have to be melted before they can be boiled. This does not require excitation of electrons, but it does require movement of electrons. Once the solid is melted, pressure will make it harder for the electrons to become excited.
Why water has a different boiling point at an elevation of 3000 meters than it does at sea level?
Water will boil at approx 100 degrees c at sea level. This is at a pressure of 1 bar.(14.7psi). As you get higher (say mount Everest) there is less pressure thus the boiling point will drop. If you own a car, you will probably know that the radiator in your car is pressurised. This is to enable the water that is used to cool down your car's engine to be able to absorb a lot more heat before it boils (something that shouldn't happen normally!). Due to the water not being allowed to boil, it will continually cool down the engine. Hope that helped!
To what temperature before water will boil?
Water (h2o) boils at 212 degrees Fahrenheit. It boils at 100 degrees Celsius This is however dependent upon atmospheric pressure. The above is true down at sea level all over the world (however minor differences can be measured contributed by high or low pressure at the time.) Very high up in the Andes mountains it is said that water boils at such a low temperature that it is even difficult to boil an egg without a pressure cooker. You can easily make an experiment regarding boiling hot water. Fill up a syringe halfway (preferably a large one) with boiling hot water. Plug the hole at the end, and pull some more to make a negative pressure inside. You will see the water starting to bubble. It boils due to the lowering of the pressure inside.
Why is cooking time longer at high altitudes?
Well, honey, at high altitudes, the air pressure is lower, which means water boils at a lower temperature. So, food takes longer to cook because it's not getting as hot as it would at sea level. Basically, you're playing by different rules up there in the mountains, so you gotta adjust your cooking time accordingly.
Can you melt a diamond and mix it with calcite?
Yes you can but it would take a very hot temperature for the diamond to melt. Not any normal hot temperature. Diamond has the highest melting point (3820 degrees Kelvin, or 6416.33 degrees F.)
Why is salt added to cook pulses at atmospheric pressure?
Salt is added to cooking pulses at atmospheric pressure to enhance their flavor. It can also help the pulses retain their shape and texture during cooking. Additionally, salt can help soften the outer skins of some pulses, making them easier to digest.

Why the boiling point of water is sometimes more than 100?
The boiling temperature of water is 100° C when the air pressure on the surface of the water is equal to standard sea-level atmospheric pressure. When the pressure is less, water boils at a lower temperature. (Cooking times for some recipes are longer in Denver, because at high altitude, the cooking liquid never gets to 100° C before it boils.) When the pressure is more, water boils at a higher temperature. (That's the reason behind the pressure cooker ... pressure inside the sealed vessel is higher, so the cooking liquid can be heated to more than 100° C without boiling, which decreases the cooking time.)
What happens when pressure greater than atmospheric pressure is applied to pure water or a solution?
When pressure greater than atmospheric pressure is applied to pure water or a solution, the boiling point of the water/solution will increase. This means that the liquid will need to reach a higher temperature before it boils. Conversely, if the pressure decreases below atmospheric pressure, the boiling point will decrease, requiring a lower temperature for boiling to occur.
When the water?
When it is as cold as possible before freezing into ice, this will depend on the atmospheric pressure but generally between 0c and 4c

Is it safe to put frozen meat in a pressure cooker?
No, it is not safe to put frozen meat in a pressure cooker as it can lead to uneven cooking and potential food safety risks. It is recommended to thaw meat before using a pressure cooker to ensure thorough and safe cooking.
How can I prevent a pressure cooker from burning on the bottom?
To prevent a pressure cooker from burning on the bottom, ensure there is enough liquid in the cooker before cooking, avoid cooking on high heat for extended periods, and stir the contents occasionally to distribute heat evenly.
How can I safely and effectively pressure cook frozen meat?
To safely and effectively pressure cook frozen meat, it is important to first thaw the meat partially in the refrigerator before cooking. This will ensure that the meat cooks evenly and thoroughly. Once partially thawed, you can then follow the instructions for pressure cooking the meat, making sure to adjust the cooking time to account for the fact that the meat was frozen. It is important to always follow the manufacturer's guidelines for your specific pressure cooker to ensure safe and effective cooking.
How can I prevent food burn in my Instant Pot while cooking?
To prevent food burn in your Instant Pot while cooking, make sure to add enough liquid, avoid overfilling the pot, deglaze the bottom before pressure cooking, and follow the recommended cooking times.
