Water vapour particles are most likely to phase change into liquid particles if the vapour particle come into contact with A COOLER SURFACE.
For a liquid to change to gas, it has to absorb enough energy to break the chemical bond that is holding the liquid particles together. When a liquid change to gas it is called vaporization. When a vapour, for instance water vapour comes in contact with cooler surfaces they lose energy and get converted back to the liquid state; this process is called condensation.
T cells and B cells are similar because they both deal with fighting of viruses.
Answer:
2. 
3. 
Explanation:
Hello there!
2. In this case, we can evidence the problem by which volume and temperature are involved, so the Charles' law is applied to:
Thus, considering the temperatures in kelvins and solving for the final volume, V2, we obtain:
Therefore, we plug in the given data to obtain:
3. In this case, it is possible to realize that the 3.7 moles of neon gas are at 273 K and 1 atm according to the STP conditions; in such a way, considering the ideal gas law (PV=nRT), we can solve for the volume as shown below:
Therefore, we plug in the data to obtain:
