The thickness of the ozone layer (for earth) and the atmosphere.
Mercury is the closest planet to the sun but it isn’t the hottest because it has no atmosphere. Although Venus is the second planet from the sun, it is the hottest because of it’s thick atmosphere and the clouds that trap heat in.
Maybe for the first the hand because there are so many joints that do so many movements and functions.
For the second, the tongue because there are so many taste buds that need to sense and taste and move.
I hope that helps, that's what I remember from elementary school. XD
The three types of heat transfer are conduction convection and radiation. <u>Explanation:</u>
- Heat transfer happens only when there is said to be a temperature difference. (i.e) heat transfer occurs with a higher temperature region to a lower temperature region.
- Heat is transferred usually via some medium in the case of convection and conduction whereas in the radiation no medium is required ( i.e it take place in a vacuum ).
- Conduction is a type of heat transfer that is mainly a character for the conducting and semiconducting solid material.
- Convection is the heat transfer method that usually takes place in the liquids and gases.
- Radiation is the heat transfer process in which heat is transferred via infrared or electromagnetic waves.
Answer: When a material is heated or cooled, two changes may happen to the particles within the material: Chemical bonds between the particles may form, break or stretch. There is a change in the chemical potential store of energy in the material. The material will heat up or cool down as the particles within it gain or lose speed.
