Question

heat transfer between two substances is affected by specific heat and the
chemical composition of the substances.
state of matter of the substances at room temperature.
thermal equilibrium of the substances.
amount of time and area of physical contact between the substances.

Explanation:

Heat transfer rate depends on factors like specific - heat. The amount of time substances are in contact and the area of physical contact also impact heat transfer. Larger contact area and longer time allow more heat transfer. Chemical composition affects specific - heat but the question asks for an additional factor. State of matter and thermal equilibrium are not the main additional factors for heat - transfer rate compared to contact time and area.

Answer:

amount of time and area of physical contact between the substances.
