Question

2. The collision of molecules within a substance results in the transfer of energy by
i) insulation ii) radiation iii) convection iv) conduction

Answer 1

Answer:

As heat is applied to a substance the energy of the particles of the substance increases. This causes the molecules to vibrate, rotate, and move from place to place more rapidly. As the kinetic energy of the particles increases, they collide with each other and with the walls of the container.
