Answer:
Both conduction and convection need matter to transfer thermal energy.
Conduction involves collision of particles, while convection involves the movement of a liquid or gas.
Explanation:
There are three ways in which heat is transmitted:
1. By Conduction, when the transmission is by the direct contact (through collisions).
2. By Convection, heat transfer in fluids making a current created by less dense fluids floating and more dense fluids sinking (like water or the air, for example).
3. By Radiation, by the electromagnetic waves (they can travel through any medium and in vacumm)
Therefore, both conduction and convection need matter to transfer thermal energy (unlike radiation).
Answer:
Rutherford
Explanation:
Basic principles of the Rutherford atomic model.
1. Positively charged particles are in a very small volume compared to the size of the atom.
2. Most of the mass of the atom is in that small central volume. Rutherford did not call it "core" in his initial papal but he did it from 1912.
3. Electrons with negative electrical charge revolve around the nucleus.
4. The electrons rotate at high speeds around the nucleus and in circular paths that it called orbits.
5. Both negatively charged electrons and the positively charged nucleus are held together by an electrostatic attraction force.
