False
temperature and kinetic energy have direct relation.
Answer:
See explanation
Explanation:
Crystallization is a separation technique used to obtain pure crystals of a substance from an impure mixture of solid substances.
The impure solid is dissolved in an appropriate hot solvent. This hot solvent is able to effectively dissolve the solid. However, as the solution is allowed to cool, the pure solid separates out of the solution as crystals.
The solid is now filtered to obtain the pure solid. The solid is also washed and dried to remove any solvent contaminant.
Answer: W
Explanation:
The cell in liquid W will look the smallest out of the four because of Osmosis.
Osmosis is a process by which water molecules move from an area of relatively higher concentration of water to an area with a relatively lower concentration through a selectively permeable membrane(cell membrane).
With W being saltier than the cell, water molecules will move from the cell to liquid W to balance the concentrations inside and outside the cell which will lead to the cell in W being smaller.
U need positive and negative electordoe and an electrolyte <span />
I would go with C because that seems like the best answer choice
