Answer:
4°C
Explanation:
Water is densest at 4°C. Since dense water sinks, the bottom of the lake will be 4°C.
Im not so sure but it should be the
instantaneous speed
Answer:
Solubility increases with temperature.
Explanation:
-Increasing temperatures, increases the kinetic energy that allows solvent molecules to more effectively break apart the solute molecules.
-This solute molecules are held together by intermolecular attractions which weakens in higher temperatures.
-Solubility therefore increases with increasing temperatures.
Answer: False
Explanation:
Winds are named for the cardinal direction they blow from. Hence, a wind that <em>"blows towards the east"</em>, logically should <u>come from the west </u>and is called a <em>"west wind"</em>.
In thise sense, one of the best examples of this type of wind are the <em>Westerlies</em>, which are are prevailing winds that blow from the west at midlatitudes and have the characteristic that are stronger during winter and weaker during summer.
Therefore, the statement is false.
