Answer: Option (e) is the correct answer.
Explanation:
According to Henry's Law, mass of a gas which will dissolve into a solution is directly proportional to the partial pressure of that gas above the solution.
Mathematically, C =
where, = Henry's constant
P = partial pressure
Since, concentration is directly proportional to partial pressure of a gas. Hence, more is the partial pressure more will be the number of molecules present in the liquid.
Thus, we can conclude that the statement there are twice as many gas molecules in the liquid, is true.
Answer:
Kinetic energy is directly proportional to mass
Explanation:
Kinetic energy is directly proportional to the mass of an object and also directly proportional to the square of the velocity of that object:
Notice that if we keep velocity constant and only increase the mass of a object, the kinetic energy of that object would increase, as we've already emphasized the direct relationship between the kinetic energy term and the mass term.
Let's take a simple example: assume that object 1 and object 2 are both moving at the same velocity but object 1 has a much lower mass than object 2. According to the equation, object 1 has lower kinetic energy. This object can then transform all of its kinetic energy into some other form, say, heat the ground. The heat transferred will be significantly lower than by the object 2 moving at the same velocity but having a much greater mass.
