A star is formed within the clouds of dust. These clouds of dust are scattered throughout the galaxy. These dust clouds are called as nebula. The turbulence inside the dust clouds rise to form knots. These knots along with sufficient mass causes gas and dust to collapse with the help of gravitational force. These sequence of steps leads to form a star.
Answer:
Lipids
Explanation:
Lipids can be described as hydrocarbons which are only soluble in non-polar solvents like chloroform. Lipids are non-polar and are insoluble in water. Lipids serve s an excellent source of energy storage and energy is stored in the body of organisms due to these non-polar molecules. Energy is usually stored as triglyceride which is a type of lipid. Triglycerides contain glycerol and fatty acids. Fats and oils are examples of lipids.
<span>The pairs would be:
1. increased surface area
</span>finely divided solute <span>
Increased surface area of the solute will make the solute </span>finely divided. Since the area of the solute that touches the solvent is higher. Since the area of work is bigger, then the work would be faster.<span>
2. like dissolves like
</span>matching polarity<span>
Like dissolve like because a matter tends to clump up with the same kind of polarity. Water is polar and will be a good solvent for a polar solute because they can form hydrogen bond which makes it easier to spread.
3. temperature
</span>rate proportional to kinetic energy
The temperature rate proportional to the kinetic energy, which makes the molecules move faster. A faster movement will make it spread easier. That is why higher temperature will result in higher solubility and faster rate of <span>dissolving
</span><span>
4. stirring
</span>spreads solute throughout solution
Stirring will help spread the solute. When the solution is not stirred, the solute that dissolved will be concentrated near the solute. This will decrease the rate of dissolving around it. Stirring help by moving the dissolved molecule away from the solute, makes the solute exposed more to the solvent.
