Question 4 (2 points) Which system has atoms with the highest average kinetic energy?
room temperature
non of these
cold water
warm water

warm water

Explanation:

Kinetic energy refers to the energy that possesses an object due to the motion of its molecules. Kinetic energy is positively associated with temperature. When heating water, water molecules gain kinetic energy and move faster than the molecules of cold water. In consequence, the temperature of an object can be considered as the average amount of kinetic energy that its molecules carry.

the sugar-phosphate backbone forms the structural framework of nucleic acids, including dna and rna. this backbone is composed of alternating sugar and phosphate groups, and defines directionality of the molecule.
