Explanation:
Both conduction and convection are both forms of heat transfer from one place to another.
- In conduction, there must be contact between two bodies for the process to take place but in convection, the matter moves to transfer heat.
- Conduction mostly occurs in solid substances whereas convection occurs mostly in fluids.
- Heat transfer in conduction is quite slow compared to convection which is much faster.
Example of conduction is heating of iron pot when cooking
Example of convection is the refrigerating system.
Answer:
B: They are the results of many experiments over a long period of time.
Explanation:
I think it might be A. i am not totally sure though
The process is called, Fixation
Scandium lost 3 electrons and gave them to oxygen the formula would be Sc2O3
