I think that this simulation was very informative. I had no idea that the freezer and the fridge are linked, nor did I know that the coolant is actually a chemical! This reminds me of a sewage system, as it has liquid in pipes that flows through an elaborate network and finally gets dumped into the fridge.
This anatomy of a refrigerator is very informative. I never knew how a fridge worked! It would be interesting to figure out how the people who invented the fridge figured out how to cool down food using a chemical! I search everywhere and I can't figure out what the name of the chemical they use in fridges is called. Can anyone else find the name?
That was very informative i never knew how my fridge worked and i had always wanted to know.
Sorry Brandon i could not find the name of the chemical either.
That was amazing! It's interesting how the cooling chemical took away enough heat to freeze in the freezer, but by the time it got to the right half of the fridge, it could just cool stuff down.... Amazing. :]
Its amazing how the chemical can go from such extreme heat to extreme cold in such little space
This anatomy is sooooo interesting! I had no clue how a fridge worked. Now I know that a chemical liquid can go from 95F to 0F gas. It is awesome that the cooler is in fact a chemical.
I thought this was OK. They should have been more specific on the different parts of the refrigerator. It also should have been a little bit longer. I thought it was "cool" how the fridge has the potential to freeze the food! I wonder how the freezer does it. Maybe it makes the distance from the air coming out compressing valve and the actual machine much shorter. I agree with Diana- it is awesome how a gas can go from super hot to really cold that quickly! Even though this could have been more descriptive, I enjoyed it very much. Thanks for posting this.
it was an interesting simulation, and also interesting. however, i also think it was kind of random, because refrigerators are kind of a random-ish topic in science. it was also cool how the fridge uses a chemical to cool it down. i remenber, once we had to have the chemical in our refrigerator replaced. it made our fridge and kitchen smell bad for a couple of days!
It's neat to finally know how a refrigerator works. I have wondered before. I also like the fact that it's interactive.
That was very interesting. I had no idea about how a refrigerator works.
This simulation was interesting because it gave a visual, and then it gave written information about how the refrigerator works. It was especially interesting how the air is cooled as goes through that pipe.
Its nice to know where my food is stored and how it works because I eat that food in there and I would have never guessed that you cool down food by using a chemical. Just like Brandon F. I couldn't find the name of the chemical they put in the refrigerator.

That was very interesting, I never thought a refrigerator could be soooooooooooo complicated. It made learning about a refrigerator fun
