Answer:
Metallic structure with black colour body.
Explanation:
The substance has metallic structure and black colour body will have greatest temperature among other substances because metallic structure and black colour of body heat up very quickly. Metals have free electrons which make it the best conductor of electricity and heat while on the other hand, black colour is a good absorbent which absorb heat very quickly so that's why we can say that metallic solids are the substance that have the greatest temperature.
Answer:
The difference between diffusion and active transport are as follows:-
<em><u>#diffusion</u></em><em><u> </u></em>
1.<u>Flow</u> of either solute or solvent
2.No such membrane is required.
3.It is a fast process.
3.It is a fast process.membrane.
4.Occurs in liquids as well as gases.
5.Movements are over large distances.
<em><u>#active</u></em><em><u> </u></em><em><u>transport</u></em><em><u> </u></em>
1.It involves flow of solvent molecules in
1.It involves flow of solvent molecules inone direction.molecules is in both directions.
2.lt requires partially permeable.
3.It is a slow process.
4.Occurs only in liquids.
5.The movement is over a short distance.
Experimental- amount of solution
Dependant- acidity
Control- water
If that doesn't make sense comment and I'll explain why.
