Object a has a higher temperature than object b. which statement must be true? object a is a better insulator than object b. object b is a better conductor than object a. heat will travel from object a to object b. heat will travel from object b to object a.

Answer is: Heat will travel from Object A to Object B.

Thermal conductuction is the transfer of heat through physical contact. Thermal conduction is the transfer of heat by microscopic collisions of particles.

Heat spontaneously flows from a hotter to a colder body.

The process of heat conduction depends on four basic factors:

1) the temperature gradient.

2) the cross section of the materials involved.

3) their path length.

4) the properties of those materials.

the answer is c.the valence of the atoms combine .
