Vaporisers

Latent heat of vaporisation

what is the vaporiser chamber made of?

How does the bimetallic strip work?

What are the other ways of heat compensation?

Back 1

The energy that must be added to a substance to transform a quantity of that substance into a gas. Non-linearly related to the temperature of the liquid.

The vaporising chamber made of dense metal with high specific heat capacity and high thermal conductivity to act as a heat to allow heat to move rapidly between the atmosphere and the vaporising chamber.

Bimetallic strips: consisting of two metal strips with different coefficients of thermal expansion. Acting as a cap over the bypass chamber or vaporising chamber, As temperature decreases, the strip bends, allowing more fresh gas flow to enter the vaporizing chamber.

Aneroid bellows: these are connected by a rod to a cone in the orifice of the bypass chamber. A reduction in temperature causes the bellows to contract, resulting in the cone partially obstructing the bypass channel, increasing flow through the vaporizing chamber.

partition coefficient

Saturated Vapor pressure

Back 2

Henry - for a fixed temp the solubility of a gas in a liquid, is proportional to its partial pressure in equilibrium with the liquid

Bunsen - volume of gas dissolved per litre of liquid at relevant temp, the partial pressure of gas is corrected to std temp and pressure

OStwald- volume of gas dissolved per litre of liquid at relevant temp uncorrected.

Boyle - PV=k

Partition coefficent - ratio of amount of substance in two different phases, when the two phases are equal volume and in equilibrium

SVP, At any given temperature, a point of dynamic equilibrium will come to exist where the number of molecules leaving the liquid phase equals the number re-entering it—at this point, the vapour is saturated and the pressure it exerts is known as the saturated vapour pressure (SVP).

what is the maximum fractional output concentration in the vaporising chamber?

If vaporiser dial is set to 1%, how does output relate to ambient pressure and SVP and dial setting?
