Temperature and Radiation by Mike Luciuk Page 3 of 4 Earthâs actual average temperature is 288 K. A simplified formula to determine the effective temperature of a body orbiting the Sun at a semi-major axis in AU of D AU is: 1 1 2804 1 AU A K T G D â = â (8) For example, the dwarf planet Eris has a semi-major axis of 68 AU.
1 the act or process of perspiring; the excretion of fluid by the sweat glands through pores in the skin. 2 the fluid excreted by the sweat glands, consisting of water containing sodium chloride, phosphate, urea, ammonia, and other waste products.Perspiration serves as a mechanism for excretion and for regulation of body temperature. the act or process of perspiring; the excretion of fluid by the sweat glands through pores in the skin. 2 the fluid excreted by the sweat glands, consisting of water containing sodium chloride, phosphate, urea, ammonia, and other waste products.
Carbon dioxide and some water are excreted by lungs. Other waste materials are removed in the urine.The organs and tissues participating in the excretion of waste products constitute the excretory system. A major function of the excretory system is the excretion of nitrogenous waste.These include ammonia, urea and uric acid .Excretion also helps to maintain a constant body temperature by removing excess heat and maintain a constant internal environment in association with the other system of the body.arbon dioxide and some water are excreted by lungs.
