Isotherm an isogram of the temperature of air, water, or soil. Most commonly drawn are isothermal maps showing mean monthly air temperature over a number of years, mean temperature for any period of time, or the temperature at a definite moment of time.
Two compounds having the same molecular formula but different structural formula are known as isomers. The number of isomers can be calculated from the number of chiral centres (n). The general formula is 2n. Glucose has four asymmetric carbon atoms, i.e., n = 4, so 24 = 16 isomers are possible for glucose.
