Y= 272.3 X= 14
PLEASE USE THE VALUES GIVEN AND DO THE PROBLEM WITH THE
SOLUTION
[a] How fast does the heat
from Y grams of hot tea conduct through
the sides of a styrofoam cup?
Give your answer in units of joules per second, and make reasonable
assumptions for the area and
thickness of the cup as well as temperature of the room and the
tea.
Write a question about the amount heat carried away by
convection
after you have taken X breaths on a cold
day. Then answer it. Feel free to look up reasonable
estimates of temperature, the heat capacity of air, and your lung
capacity.
[c] Write a question about how much more heat radiates away from
a
metal teapot that contains boiling water compared to one that
contains water at X degrees
Celsius.
Then answer the question.
