At higher elevations, the boiling point of water decreases, due to the decrease in atmospheric pressure. as a result, what
could be said about hard boiling an egg?
a. at higher elevations, it would take less time to hard boil an egg, because there is less atmospheric
pressure
b. at higher elevations, it would take longer to hard boil an egg, because there is a lower boiling
point, so the egg is boiling in water at a lower temperature.
c. at higher elevations, it would take less time to hard boil an egg, because there is a lower boiling
point. therefore it would take less time to achieve the boiling point
d. at higher elevations, it would take longer to hard boil an egg, because it would take longer to
achieve the boiling point.

While studying chemical reactions and conservation of matter, sarah's class conducted a variety of experiments. sarah and her lab partner found the mass of a wax candle and placed the candle in a flask. the students lit the candle and let it burn to completion. all that was left was wax and charred candle wick. per their teacher's instructions, the students found the mass of the products. their data can be seen in the data table. formulate a hypothesis the students could test to explain why the experiment did not support the law of conservation of matter. a) the students could repeat the experiment using different candles; there might have been a flaw in the candle. b) the experiment should be repeatable. the students should run several trials and then take an average of the after mass in each trial. c) the students should have someone in the class check their measurement skills as they repeat the experiment. they may have made an error using the balance. d) the students should burn the candle in a container that has some type of lid so that any gas that is a product of the reaction can be contained and massed. submit
