In a fixed volume when temperature increases , pressure does what?
Leni [432]

<u>Answer:</u>

<em>When the volume is constant the pressure increases with temperature.  </em>

<u>Explanation:</u>

<em>Gay Lussac’s law precisely explains the relation between pressure and temperature of a system which has constant volume.</em> In a system which has constant volume an increase in temperature indicates increase in temperature as well.

The reason behind the observation of this trend is the change in <em>randomness of particles of the system.  </em>

With increase in temperature the particle movement becomes random and fast. <em>The particles hit the container walls at an increased rate and the pressure of the system increase.  </em>

Give an example of two types of cells that never go through cell division once fully formed.
AnnyKZ [126]

Answer:

The two types of cells that never go through cell division once fully formed are nerve cells and muscle cells.

Explanation:

The nerve cells and the muscle cells not undergo cell division after formation, because they can never re grow or cannot be repaired once they are mature. We should take good care of it once they are matured. They just under division from being baby to teenagers after that they stop undergoing cell division. This is true for both elephants as well as human beings. This thing is also applicable in case of bones.
