The DNA molecule is a polymer consisting of several thousand pairs of nucleotide monomers. Each nucleotide consists of the pentose sugar deoxyribose, a phosphate group and a nitrogenous base which may be either a purine or a pyrimidine. Deoxyribose and a nitrogenous base together form a nucleoside.he DNA molecule is a polymer consisting of several thousand pairs of nucleotide monomers.

One way to measure the temperature of matter is. to place a thermometer in contact with it. Some of the. matterâs kinetic energy is transferred to the thermometer. if the matter is warmer than the thermometer. The. increased kinetic energy causes the particles of the. liquid in the thermometer to move farther away from. each other.
The goal of this science project is to determine which food items store more chemical energy; you will determine this by burning the items and capturing the heat given off in a homemade calorimeter.ow, let us see how to calculate the energy stored in the water for a measured increase in the temperature (in Â°C). The temperature difference times the mass of the water (in grams) will give you the amount of energy captured by the calorimeter, in calories, a unit of chemical energy.
