What is true about thermal energy heat transfer?

it goes from temperature temperature areas always in this direction.

Hotter temperature to cooler temperature areas.

Explanation:

Thermal energy defined as the energy that an object possess due to the movement of its molecules. In this process, heat is transferred from hotter to colder object. The transformation of temperature will be continued till both the objects are at same temperature.  During the transformation of heat from one object to another, the motion of the particles speeds up which results in increasing the temperature.

explanation:

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.
