Heat Transfer Questions
- Please completely answer each questions using evidence found from scholarly research.
(Provide the link of your source/s for each questions)
- Your answers must be in your own words, well thought and based on actual evidence.
- Please type your responses and turn them into Google classroom by Monday 1/7/19
1. How does an oven mitt successfully keep your hands from getting too hot when you
reach into a hot oven?
2. You have a chocolate chip cookie that recently came out of the oven. You touch the
outside of the cookie and it seems cool enough to eat. As you bite into it, a melted
chocolate chip burns your tongue. How does this happen?
3. When standing in a cool room that has both carpet and tile flooring with one bare foot on
each type of material, the tile will feel colder than the carpet. Please explain why.
4. You get into a car that has been sitting in the sun on a hot day. You notice that the metal
part of the seat belt buckle feels like it burns you but the plastic part of the seat belt
buckle does not. Why? Please explain.
5. You are baking cookies and have just pulled two cookie sheets out of the oven. The
cookie sheets have the same thickness (which is very thin) and same ratio of width to
length, and one of the cookie sheets is twice as long as the other. Will one cookie sheet
cool more quickly than the other will? If so, which one cools faster and why? If not, why
do they cool at the same rate?
6. You are planning to make punch and you would like to cool it with ice. At the store, there
are 2 different one-pound bags of ice to choose from: one that contains large ice cubes
and one that contains small ice chips. You only want to purchase one bag of ice and will
add the entire bag to the punch.
a) Would one of the bags cool the punch at a faster rate? If so, which one and why?
If not, why?
b) Would one of the bags of ice cool the punch to a lower temperature? If so, which
one and why? If not, why?
7. In a recent movie about snakes and a plane, there was a need to turn the air circulation
system on the plane off. In the movie, the inside of the plane became hotter once the air
system was turned off. In real life, do you think the inside of the plane would get warmer
or cooler without the air circulation system (do you think the air circulation system acts
as a heater or air conditioner)?
