A python can detect thermal radiation from objects that differ in temperature from their environment as long as the received intensity of thermal radiation is greater than 0.60 W/mĀ². Your body emits a good deal of thermal radiation; a typical human body has a surface area of 1.8 mĀ², a surface temperature of 30Ā°C, and an emissivity e = 0.97 at infrared wavelengths. As we've seen, the intensity of a source of radiation decreases with the distance from the source.
If you are outside on a cool, dark night, what is the maximum distance from which a python could detect your presence?

The magnitude of the amount of energy released by burning a fuel source, measured in energy per unit mass, is called its fuel value. note that the fuel value is the negative of the isobaric specific heat of combustion for the fuel. if all the energy obtained from burning 1.23 pounds of butane with a fuel value of 10.85 kcal/g is used to heat 128.0 kg of water at an initial temperature of 18.3 Ā°c, what is the final temperature? note that 1 lb = 453.6 g.
