John Dalton studied the behavior of gas mixtures. Each component of a gas mixture behaves independently of the others.. Example: A given amount of oxygen exerts the same amount of pressure whether it is alone or in the presence of other gasses.. Describe how you could get drinkable fresh water from salt water..

Many linear inverse problems are solved using a Bayesian approach assuming Gaussian distribution of the model.. We show the analytical solution of the Bayesian linear inverse problem in the Gaussian mixture case.. .. Different substances, carried by a gas, travel through a column packed with a solid material at different speeds, so that they become separated the number of peaks on the output of a gas chromatograph shows the number of compounds .
