Suppose a hippopotamus on land receives 73 units of heat per minute due to solar radiation and 52 units of heat per minute due to infrared radiation. It emits 39 units of infrared radiation and it loses 66 units of heat per minute through evaporation. The hippopotamus gains 45 units of heat per minute through its metabolism. Overall, its heat energy is increasing by 50 units per minute (i.e. its temperature is increasing). Delta Hanimal = SR + IRin - IRout + Hcony + Hcond - Hevap + Hmet Based on this information we can conclude that the combination of conduction and convection is the animal, and that its current temperature is than the ambient temperature. Select one: a. cooling; warmer b. warming; warmer c. cooling; cooler d. warming; cooler

Question
Suppose a hippopotamus on land receives 73 units of heat per minute due to
solar radiation and 52 units of heat per minute due to infrared radiation. It
emits 39 units of infrared radiation and it loses 66 units
heat per minute
through evaporation. The hippopotamus gains 45 units of heat per minute
through its metabolism. Overall, its heat energy is increasing by 50 units per
minute (i.e. its temperature is increasing).
Delta Hanimal = SR + IRin - IRout ± Hconv ± Hcond - Hevap + Hmet
Based on this information we can conclude that the combination of
conduction and convection is
the animal, and that its current
temperature is
than the ambient temperature.
Select one:
a. cooling; warmer
b. warming; warmer
c. cooling; cooler
d. warming; cooler
