Save the Penguins!
The penguins in the Antarctic need this environmental feature as part of their habitat, but global warming is continually melting it.
Ice
A difference in this metric is the driving force of heat transfer.
Temperature
what is 10% of 8?
0.8
The heat lamp lets off this type of heat transfer.
Radiation
This material stops heat transfer.
Insulator
New diet coke bottles give you 50% more Diet Coke. If the original bottle is 2 Liters, what would be the size of the new bottle?
3 Liters
The air surrounding the penguin promotes this type of heat transfer.
Convection
This material promotes heat transfer.
Conductor
Let’s say the useful life of an iPhone in 5 years. With better design and engineering, we can increase the useful life by 20%. How long would the new useful life be?
6 years
As you held the penguin, it began to melt due to contact with your hand. This type of heat transfer is responsible.
Conduction
This is a specific material that you could have used to build your penguin home that would do the best job reflecting radiation heat transfer.
Mylar
Amazon is working on cutting costs for packaging. The original packaging for a tv weighs 12 pounds. Amazon’s goal is to decrease the new package weight to 90% of the original. How much should the new packaging weigh?
10.8 pounds
If a penguin ice cube originally weight 9 grams and 2 grams melted under the lamp, what percentage of the penguin by mass melted?
~22%
Cotton balls, foam, felt and bubble wrap all share this in common that help them become good insulators.
Air pockets/ Trapped air
A computer weighs 2.3 pounds. 40% of the computer (by weight) can be recycled. How many pounds of computer parts are able to be recycled from 100 computers?
92 pounds
