Answer:
Argon
Explanation:
The average kinetic energy of the particles in a gas is given by
where
m is the mass of the particles
v is their rms speed
The average kinetic energy of the particles in a gas can also be written as
where
k is the Boltzmann's constant
T is the absolute temperature of the gas
Combining the two equations,
We can re-write the equation as
We see that:
- The speed is directly proportional to the square root of the temperature
- The speed is inversely proportional to the square root of the mass of the particles
Therefore, if the two gases are at same temperature, the particles will move faster in the gas with lighter particles (smaller mass).
Since Krypton atoms have larger mass than Argon atoms, it means that atoms in Argon move faster than in Krypton.
Lithium atoms contain 3 protons, 3 electrons, and 4 neutrons, so the statement is Correct
Answer:
The water is the medium of the wave
Answer:
Im not sure what you mean but I hope what I wrote helps you!
The Law of Conservation of Matter says that the amount of matter stays the same, even when matter changes form. Sometimes it may seem that matter disappears during a science experiment, but this law tells us that matter cannot magically appear or disappear, it simply changes from one form to another.
