- 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 insteadWhen an object is heated its temperature definitely increases? a) True b) FalseDuring a winter time in the past, Chicago temperature was -25°F. What are corresponding values on the Celsius and Kelvin scales? detailed solution with all the explanations
