Question

E. Differentiate between the following.
1. Conduction and convection
2. Celsius and Kelvin scale
3. Expansion and contraction​

Answer 1

Answer:

1:In conduction, heat transfer takes place between objects by direct contact. In convection, the heat transfer takes within the fluid. In radiation, heat transfer occurs through electromagnetic waves without involving particles.

2:The Kelvin scale is preferred in scientific work, although the Celsius scale is also commonly used. ... Because the difference between the freezing point of water and the boiling point of water is 100° on both the Celsius and Kelvin scales, the size of a degree Celsius (°C) and a kelvin (K) are precisely the same.

3:The difference between Contraction and Expansion. When used as nouns, contraction means a reversible reduction in size, whereas expansion means the act or process of expanding.
