If atmospheric pressure at lake tahoe is 649 torr, what will be the boiling point of water there?

The boiling point of water at lake Tahoe is 95.6°C.

The variation of boiling point of water with pressure is determined by using the Clausius- Clapeyron equation.

Here,

P₁ is the pressure at temperature T₁, P₂is the pressure at temperature T₂;ΔHvap is the enthalpy of vaporization of water,and R is the universal gas constant.

rewrite the expression for T₂.

The boiling point of water at atmospheric pressure of 760 torr is 373 K.

Substitute 760 torr for P₁, 649 torr for P₂, 373 K for T₁, 8.314 J/K mol for R and 40660 J/mol for Δ H_vap and simplify.

Express the temperature in Celcius.

the higher the current the higher the mag field around it the higher the influence on the compass

energy stored in the capacitor= 9.72 x 10⁻⁴ j

explanation:

the energy stored in the capacitor is given by

e= 1/2 c v²

e= energy stored

c= capacitance= 1.5 µc= 1.5 x 10⁻⁶f

v= potential difference=36 v

so energy stored= e= 1/2 (1.5 x 10⁻⁶) (36)²

energy stored= 9.72 x 10⁻⁴j
