boiling point By: Athena Tsai, Jimmy Peebles, Preston Doane, and Donla Gyalnub

2 What is boiling point? Boiling is the state of something steaming or bubbling up under the action of heat. The boiling point of a liquid is the temperature at which the vapor pressure is the same as the gas pressure above it. The normal boiling point of a liquid is the temperature at which the vapor pressure is equal to one atmosphere (760 torr).

3 differences between substances
The boiling point varies between different substances. For instance, the boiling point of hydrogen is -423°F(- 253°C). Whenever something boils, bubbles form in the liquid and eventually float to the top, releasing gas.

4 boiling with different types of matter
When a solid goes directly from its form to a gas it is called sublimation. So we wondered if gas can go directly to a solid too. The answer is yes and it’s called deposition. Gas can also turn into plasma and this is called ionization.

5 differences between situations
The boiling point also may vary when you are in different places. For example, if you are at a higher elevation, than the temperature of the boiling point will be lower. If you are at a lower elevation, than the temperature of the boiling point would be higher. This is because the definition of boiling is when the vapor pressure of the gas leaving the liquid is the same as the pressure applied to the liquid by its surroundings. That is why substances boil at different temperatures in different places.

6 real world references Boiling point can refer to a lot of real world situations. You may need to know how fast and at what temperature your egg will cook. You may also want to know how the boiling point will differ when you are at different elevations like when you go to the mountains or when you go somewhere lower like the valley.

7 Investigative Questions
One question is, would ice turn immediately into gas if you put it on a small flame or would it turn into liquid and extinguish the flame? Another question is, would wind effect the boiling point of an object?
