Answer:
T_2= 234.37 K
Explanation:
According to Claperyon, we know that
![P_2-P_1= \frac{\Delta H_{fus}}{\Delta V}\times\frac{T_1}{T_2}](https://tex.z-dn.net/?f=P_2-P_1%3D%20%5Cfrac%7B%5CDelta%20H_%7Bfus%7D%7D%7B%5CDelta%20V%7D%5Ctimes%5Cfrac%7BT_1%7D%7BT_2%7D)
P_1= Atmospheric pressure 760 mm Hg
P_2 = pressure at the bottom of the column
= 10×10^3 mm of Hg+ 760 mm of Hg
= 10760 mm of Hg
now,
P_2-P_1= 10760-760= 10^4 mm
P_2-P_1 ( in pascals) = 10^4× 133.322= 1333220 mm
the enthalpy of fusion (ΔH-fus) of mercury is 2.292 KJ/mol
use the above equation to calculate ΔT as follows
![1333220= \frac{2292}{0.517\times10^{-6}}\times ln\frac{T_2}{234.3K}](https://tex.z-dn.net/?f=1333220%3D%20%5Cfrac%7B2292%7D%7B0.517%5Ctimes10%5E%7B-6%7D%7D%5Ctimes%20ln%5Cfrac%7BT_2%7D%7B234.3K%7D)
therefore, T_2= 234.37 K
Answer:
The answer is "The last choice".
Explanation:
Please find the complete question in the attachment.
In an external electric field, its electrical energy at positive charge becomes directed to just the electrical domain. Therefore it will speed towards its base plate whenever cyber one is released to rest at h0. It was never going to reach the top plate. Thus, the last choice corrects because in this the cyber-on never reaches its upper stage.
Explanation:
binary number is a number expressed in the base-2 numeral system or binary numeral system, which uses only two symbols: typically "0" and "1".
Most of the momentum is transferred to the ball on top. Since the collision in this situation is elastic, momentum is conserved, meaning the momentum of both balls before hitting the floor is equal to the momentum of both balls right after the collision.
