Thermos Experiment

I made my thermos by wrapping tin foil around a styrofoam cup numerous times. One mistake, though, was not making it a close system, my thermos had no lid. Everyone should have started at 353.15 K and from there recorded 30 minutes of decreasing temperature, ours went down 27 K within 30 minutes. If it was a closed system maybe the thermos would have decreased slower. 

Week 10 Reflection.

At the beginning of the week we did a lab involving cold water and what the affects would be after adding less volume of hot water or more volume of room temperature water. In the end, adding the room temp. water increased the ice water more than the hot water did. What happened was, since the volume of the room temp. water was larger than the hot water container, it warmed the ice water up more. If they were the same volume the hot water would have made the ice water warmer.

Week 9 Reflection

Well this week we learned about pressure and temperature a bit more. Dealt with barometers and thermometers, and even made a barometer. A barometer measures pressure, atmospheric pressure. A simple way of making a barometer is by stretching a balloon over a glass jar with a straw on top, when there's low pressure outside the balloon is inflated a little, when there's high pressure the balloon dips down a bit.
