Globally, the winter of 2014-15 was the warmest winter on record at that time, but it sure didn't seem that way for most of the eastern United States. This region
experienced record-low temperatures and extreme snowfall, especially in the northern
and coastal areas. During this period of extreme cold and snow, it was not uncommon
to see comments on social media disputing climate change. For example, some
commenters took pictures of huge piles of snow and added comments such as. "This
doesn't look like global warming.
B
Do these commenters have a point? Should extreme snowfall over the course of a
season cast doubt on the theory of global climate change? Make a scientific argument
explaining why you agree or disagree with these commenters

answer : one can design an experiment using a liquid and an additive that can be added to the liquid and observe the chemical changes in the reaction species.

one would need a beaker which is filled with a known amount of the liquid in which thermometer is placed to measure the temperature changes; after addition of the additive to the liquid solution one can note down the temperature change and find whether the reaction is endothermic or exothermic in nature. by subtracting the initial temperature value with the final temperature one can find the temperature changes.

various combinations of liquid and additive can be used. liquid in this case can be a known quantity of water and additives can be epsom salt or without epsom salt the experiment can be conducted to notice the changes. water and ice, hydrogen peroxide and dry yeast, vinegar and baking soda,etc.

it should have an internal chamber and two thermometers sticking out of the top. the internal chamber will also be closed off from the outside.
