Describe what is the vapour pressure? When the temperature is 100 degree Celsius, what is the vapour pressure of water?
Solutions
Expert Solution
Ans:
The pressure exerted by vapours of a liquid on the surface of the liquid at equilibrium is the vapour pressure of given liquid. Vapour pressure of a solution containing non volatile solute is always less than the vapour pressure of pure solvent.
At hundred degree Celsius, the vapour pressure of water is 760 mm Hg or 1 atmosphere.
The pressure exerted by vapours of a liquid on the surface of the liquid at equilibrium is the vapour pressure of given liquid.

4. Suppose that we have a set of temperature measurements in
degree Celsius whose variance is
25(◦C)2. What is the standard deviation of same set of
measurements in degree Fahrenheit?
(The formula connecting degree Celsius and degree Fahrenheit
is: Y (◦F) = 1.8X(◦C) + 32.)

Temperature Conversion Menu (100 pts)
The three common temperature scales are Celsius, Fahrenheit and
Kelvin. The conversion formulae for each of the scales is shown
below (where °C, °F and K represent the temperatures in degrees
Celsius, degrees Fahrenheit and Kelvin respectively):
Celsius to Fahrenheit: °F =
(9.0/5) ´ (°C) + 32
Celsius to Kelvin: K = °C +
273.15
Kelvin to Celsius: °C = K –
273.15
Kelvin to Fahrenheit: °F =
(9.0/5) ´ (K – 273.15) + 32...

300% excess air having a dry bulb temperature of 25 degree
celsius and relative humidity of 60% is used to fully combust 1
kg/hr of methane in a boiler and the heat of reaction is used to
generate steam. Hot water enters the boiler as a saturated liquid
at 102 degree celsius and leaves as superheated at 40 bar and 400

When a piece of copper, at a temperature of 256.0 degrees
Celsius, is added to 255 grams of water at a temperature of 20.0
degrees celsius, the temperature of the resulting mixture is 24.0
degrees celsius. If the specific heat of copper is 0.385 J/g x
degrees celsius, what was the mass of the copper? The specific heat
of water is 4.184 J/g x degrees celsius.
