A study of bushfires has shown that as a fire passes, the air temperature is approximately 800 K for about one minute. Consider an animal in these conditions. Assume that the animal's surface can be characterised by an area of 0.4 m2, a temperature of 34 C and an emissivity of 0.9. (a) Explain the processes by which heat is transferred in this situation. (2 marks) (b) Calculate the nett rate at which radiant heat is transferred to, or from, the animal in these conditions. Specify whether it is to, or from, the animal's body. (2 marks) (c) What is the total amount of radiant heat transferred during the time of the fire passing? (1 mark)
