Avoid meats such as liver, kidney and sweetbreads, which have high purine levels and contribute to high blood levels of uric acid. Selected seafood. Avoid the following types of seafood, which are higher in purines than others: anchovies, herring, sardines, mussels, scallops, trout, haddock, mackerel and tuna.
If the pressure of a gas is held constant, its volume is proportional to the temperature. As the temperature increases, the atoms move faster and require more space so that they strike the walls of the container with the same net force. The volume increases. If the temperature of a gas is held constant, its pressure is inversely proportional to the volume. If the volume of a gas is decreased, then the same number of atoms moving at the same speed (because the temperature has not changed) will strike the walls of the container more often.
1 If the number of gas molecules and the temperature remain constant, then the pressure is inversely proportional to the volume. 2  If the temperature changes and the number of gas molecules are kept constant, then either pressure or volume (or both) will change in direct proportion to the temperature.
