Which of these describes conduction

a. transfer of heat by the actual movment of warmed matter
b. transfer of heat between two objects that are touching
c. the process in which energy is released by molecules
d. the process in which energy is emitted by one object , transmitted through space, and obsorbed by another

b. transfer of heat between two objects that are touching

Explanation: MODES OF HEAT TRANSFER

1. Conduction: This type of heat transfer happens when there is direct contact between the two object.

2.  Convection: This type of heat transfer happens when there is a movement of fluid (liquid or gas). due to generation of convection currents as hotter fluid moves downwards and colder fluid moves upwards.

3. Radiation: This type of heat transfer happens when there is direct transfer of energy through space.

a. Transfer of heat by the actual movement of warmed matter is convection.

b. Transfer of heat between two objects that are touching is conduction.

c. The process in which energy is released by molecules is called as exothermic reaction.

d. The process in which energy is emitted by one object , transmitted through space, and absorbed by another is radiation.
