A scientist has two samples of a substance. Both samples have the same temperature. The average kinetic energy of the two samples is the same but the total kinetic energy of the particle with a mass of 20 g is greater than the one with a mass of 10 g.
From the given information:
- sample A = 10 g
- sample B = 20 g
The average kinetic energy is relative to the temperature and the temperature can be used as a determining factor when measuring the average kinetic energy. From the given question, it was stated that both samples have the same temperature, as such, we can infer that they have the same average kinetic energy.
The total kinetic energy of an object is equal to the sum of the kinetic energies produced from every kind of motion. The total kinetic energy of a particle is affected by the speed of the motion and the mass of the sample. As such, the mass of the sample with 20 g will have a greater total kinetic energy than a mass with 10 g.
Therefore, from the above explanation, we can conclude that the mass of the average kinetic energy of the two samples is the same but the total kinetic energy of the particle with a mass of 20 g is greater than the one with a mass of 10 g.

Pluto was ruled not a planet anymore because it is a "dwarf planet"
Apparently, the International Astronomical Union's (IAU) definition of a planet includes that a planet should be part of a body that would orbit the sun.
According to the IAU, there are three criteria's that contribute to a planet being called a planet.
1. It is within orbit around the Sun.
2. It has a sufficient mass to assume a nearly round shape
and 3. It has "cleared the neighborhood" around it's orbit.
Pluto only so happens to meet 2 of these requirements, not including the third option.

<u>Answer:</u> The value of 
for the equation is 
<u>Explanation:</u>
The given chemical reaction is:
The chemical equation for which the equilibrium constant is to be calculated follows:
As, the equation is the result of the reverse of given reaction. So, the equilibrium constant for the equation will be the inverse of equilibrium constant for the given reaction.
The value of equilibrium constant for the equation is:
We are given:
