Name two forms of thermal energy transfer between a high temperature room and a glass of water with ice in it.
If you are trying to rapidly melt chocolate which of the following would melt faster and why? 50 oz of Chocolate or 100 oz of Chocolate
50 oz, the smaller amount of matter means the temperature will heat up faster
You touch hot cocoa to your tongue, what kind of heat transfer is occuring?
Conduction
Beams of sunlight travel through space and warm the atmosphere, what kind of heat transfer is occuring?
Radiation
A pressure pipe bursts and steam escapes and quickly fills the ceiling of a room, what kind of heat transfer is occuring?
Convection
Mr. McCammon is making tacos for dinner. He placed a pan on the stove and watched as the bottom of the pan became red hot. What type of thermal energy transfer occured between the pan and the stove and describe how the energy transfered.
Conduction, the thermal energy transfered from the warmer stove to the cooler pan.
Describe the heat transfer between a warm bag of vegetables placed in a freezer.
Ther warmer bag of vegetables will transfer thermal energy into the cooler freezer.
Panera soup is frozen and brought to a boil when people order. The buisness notices that that the 10lb bag of carrot soup heats up slower than the 8lb bag of broccoli soup. Describe why.
The broccoli soup heats faster due to the smaller amount of mass. Less mass heats faster.
Which singular material (no outside heat sources) would keep you warmer in the winter and why? Iron or Fleece
Fleece, because it is an insulator/minimizer, slows the transfer of thermal energy away from you
