Answer:
There should be the refraction for light to change a material.
The new lowered freezing point of the benzene mixture is determined as 2.4°C.
<h3>
Effect of impurities in freezing point</h3>
The presence of impurities lowers the vapour pressure of the solution since the concentration of the solution is increased.
Change in temperature of the new mixture = 0.613 x 5.5°C = 3.1 °C
New freezing point = 5.5°C - 3.1°C = 2.4°C
Thus, the new lowered freezing point of the benzene mixture is determined as 2.4°C.

Stopping your car; using the brakes
Answer:
Explanation:
Since the atmosphere is fixed to the earth by gravity and rotates with the earth, there would be no circulation if some force did not upset the atmosphere's equilibrium. The heating of the earth's surface by the sun is the force responsible for creating the circulation that does exist.
