Answer : The atmospheric pressure of water if boiling at 81 °C will be 369 mmHg.
Explanation : The vapor pressure of boiling water can be calculated using the Antoine Equation:
log P = A - ,
where P is the pressure in mmHg,
A = 8.07131,
B = 1730.63
C = 233.426
and T = temperature in °C (81°C)
Substituting the given values, we get,
Log P = 8.07131−
Therefore, Log P =8.07131 − 5.5041 = 2.567.
Now, P = =369 mmHg.
Hence, the atmospheric pressure will be 369 mmHg.

Answer : The mass lost would be,
Solution : Given,
Energy released =
Speed of light 'c' =
Formula used :
where,
E = energy
m = mass
c = speed of light
Now put all the given values in the above formula, we get
Therefore, the mass lost would be,
B)can be deduced from the balanced equation for the reaction
C)must be measured experimentally
D)depends on the concentrations of reactants
E)is the inverse of the entropy of the system
