Question

State the differences between:
1. conduction and convention
2. alpha particles and beta particles

Answer 1

Explanation:

2.The alpha particle is a helium nucleus; it consists of two protons and two neutrons. It contains no electrons to balance the two positively charged protons. ... Beta particles are emitted by neutron rich unstable nuclei. Beta particles are high energy electrons.

1.Conduction is the transfer of heat by direct contact; requires a solid. Convection is the transfer of heat in a fluid; can be a liquid or a gas. Both require matter.

Answer 2

Answer:

1: in conduction heat transfers takes place between objects by direct contact. in convection the heat transfer take place in fluids

2: alpha particles carry a positive charge

beta particles carry a negative charge and gamma rays are neutral
