Is it endo or exo? Calculate heat transfer of popsicle and tea
1. Do Now: Monday 4/30
Predict if the following process is endo or exothermic
and perform the calculation to check your answer: A
popsicle (made of ice) is in the freezer at -4oC. You
take it out of the freezer and the temperature
increases to -1oC. What is the heat transfer?
2. Todays Learning Goals:
SWBAT identify and calculate exothermic and
endothermic reactions.
3.
4. Exit Slip:
A hot cup of tea (mostly water) at 98oC is left to sit
o
out. The temperature eventually drops to 22 C. The
amount of energy released by the tea over time is
69956 J. What is the mass?
