Answer: D :a brown bear hibernates and becomes inactive during winter.
Explanation:
Secondary Alcohol is converted into corresponding Cyanohydrin in two steps;
Step 1: Oxidation of Sec. Alcohol: Secondary Alcohols when treated with Sodium Dichromate in acidic medium are converted into corresponding Ketone.
Step 2: Reduction of Ketone using HCN: Ketone is reduced to Cyaynohydrin when treated with CN nucleophile. A nucleophillic addition reaction takes place.
Answer: Pumping can affect the level of the water table. In an aquifer, the soil and rock is saturated with water.
Explanation:
As the temperature of a gas increases, the average kinetic energy of the gas particles increases and the average speed of a gas particle increases.
According to the kinetic theory of gases, all gases are made of microscopic molecules that move in straight lines until they bump into another gas molecule or object. This transfer of energy causes molecules to move around faster and bump into each other more.
Kinetic energy is proportional to the speed of the molecules. As the speed of the colliding molecules increases, so does the total kinetic energy of all the gas molecules. It's pretty difficult to measure the speed of an individual gas molecule.
Instead, temperature can be used as a measure of the average kinetic energy of all the molecules in the gas. As the gas molecules gain energy and move faster, the temperature goes up. This is why Amy feels warmer!
To determine the average kinetic energy of gas molecules, we need to know the temperature of the gas, the universal gas constant (R), and Avogadro's number (NA).
