Answer:
T_2= 234.37 K
Explanation:
According to Claperyon, we know that
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
therefore, T_2= 234.37 K
Answer:

Explanation:
Gravity is a force because it pulls down on objects.
Answer:
13.15 watt
Explanation:
work done = Force x displacement
W = 25.3 x 1.3
W= 32.89 J
Power = Work done / time
Power = 32.89 / 2.5
Power = 13.15 Watt
