The end of the iron fire poker that you are holding gets warm even though it is not directly in the fire. the motion of the iron atoms is responsible for this heat transfer.

true
false

False

Explanation:

The heat transfer can be achieved in three ways:

1. Conduction: This type of heat transfer happens when there is direct contact between the two objects. The motion of the atoms is responsible for this heat transfer.

2.  Convection: This type of heat transfer happens when there is a movement of fluid (liquid or gas) in which convection currents are produced due to the movement of hot fluid upwards and cold fluid downwards. This happens as the density of hot fluid decreases and thus it moves upwards.

3. Radiation: This type of heat transfer happens when there is direct transfer of energy through space when there is no contact between the two objects.

Thus the heating of the end of the iron fire poker that you are holding though it is not directly in the fire is not due to the motion of the iron atoms.

the number of protons in the nucleus of a given element. has slight luster and conducts electricity at high temperatures like metal.but like a nonmetal,boron is brittle and does not conduct electricity well at low temperatures. in graphite, carbon is a soft,brittle solid.it is reflective,ductile,or malleable.

the answer is option a.
