You are high up in the mountains and boil water to make some tea However, when you drink your tea, it is not as hot as it should be. You try again and again, but the water is just not hot enough to make a hot cup of tea. Which is the best explanation for this result? High in the mountains, the air pressure is significantly less than 1 atm, so the boiling point of water is much lower than at sea level.

Respuesta :

Answer:

The air pressure is significantly less than 1 atm, so the boiling point of water is much lower than at sea level.

Explanation:

This has to do with Gay Lussac's Law (a.k.a pressure law) which in essence means that when pressure goes up, temperature goes up and when pressure decreases, temperature decreases. This is why when the air pressure is signifcantly less than 1 atm (the pressure at sea level), the boiling point of water is much lower than at sea level.

The best explanation for the scenerio is :  High in the mountains , the air pressure is significantly less than 1 atm, so the boiling point if water is much lower than at sea level.

The higher you go above sea level the lower the air pressure and this will significantly affect the temperature at which certain liquids ( water ) will boil. therefore the boiling point of water will be  much lower than at sea level.

In this scenerio the application of Gay Lussac's law comes in

Gay Lussac's law states that the pressure of gas is directly proportional to its temperature at constant volume

Hence we can conclude that The best explanation for the scenerio is :  High in the mountains , the air pressure is significantly less than 1 atm, so the boiling point if water is much lower than at sea level.
