- why is the answer positive if the change in temperature is negative (initially at 100C then went down to 34C) isnt change in temperature Tf-Ti, so it would be 34-100 =-66C? also energy is being transferred out so wouldnt the answer be -6910 insteadThere are 4 people in an Igloo (half shpere) with an r of 2.4m and each person emits 120 watts of heat. How thick must the igloo walls be to maintain an inside tmep of 10C if outside temp is -17.8C. (Heat is only lost in this problem through conduction) k of ice blocks is 0.32j/smC.
