Boiling Water with Ice Lab
Purpose: The purpose of this experiment was to demonstrate how the pressure inside and outside the flask was used to make the water boil.
Hypothesis: If we heat water inside a container, then place a rubber stopper in the flask then the water will boil if ice is added to the top because the ice will cool down the water molecules and condense the molecules inside the container causing the pressure inside to decrease and the water to boil.
Data/observations:
Qualitative Observations:
When placing the ice on top of the flask, it took several seconds for the water to begin to boil
The rubber stopper was hard to take out because the flask created a vacuum seal

The procedure for this lab is fairly simple. First fill up an erlenmeyer flask with 50 mL of warm tap water, then put it on a hot plate and bring it to a boil. Inside a tray to catch any spills set up a ring stand about 6 inches high. After the water has started to boil remove it from the hot plate and let it cool slightly by setting it on the lab table, after about a minute place the rubber stopper in the flask and carefully flip the flask over and place it in the ring stand. Rub an ice cube on the top of the flask and watch it boil. Then clean up the lab when you are

The higher the altitude the lower the boiling point of a substance or in this case water will be. This is because the higher the altitude the lower the atmospheric pressure and thus the vapor pressure needed to boil is lower making the boiling point lower. 6) This affects food preparation at higher altitudes as well. Food labels suggest cooking food for longer times at higher altitudes because the boiling point is the hottest a substance will get, so for if you are at high enough altitudes water will boil at much lower temperatures and it will not get any higher. This means that food will take longer to cook at lower temperatures than the regular amount of time at the normal boiling
