Answer:
The boiling point decreases as the volume decreases.
Explanation:
The Temperature - Volume law otherwise called as Charles law is applied, which says that the volume of the given gas at constant pressure is directly proportional to the temperature measured in Kelvin. As the volume increases, the temperature also increases, if the volume decreases, then the temperature also decreases.
As per the Charles law, here the volume is decreased from 50 ml to 25 ml so the boiling point also decreases.
Tarnish is Ag2S-silver sulfide and the oxidation state of silver is +1
Explanation:
Since the wheel moves up and down, the position that represents the potential energy is that which has the maximum height from the ground.
Potential energy is the energy at rest of a body.
It is given as:
Potential energy = m x g x h
m is the mass of the body
g is the acceleration due to gravity
h is the height of the body
We can see that mass and height are directly related to the potential energy a body exerts.
The higher the wheel from ground, the higher its potential energy.

<h2>Answer:</h2>
The mass of the system will remain the same if there is no conversion of mass to energy in the reaction.
<h3>Explanation:</h3>
- If the system is closed, then according to the law of mass conservation the mass of the reaction system will remain the same.
- <u><em>Law of conservation of the mass: In simple words, it is described as the mass of a closed system can never be changed, it may transfer from one form to another or change into energy.</em></u>
- But if the reaction involves energy transfer like heat or light production, in this case, the mass can be changed.
