An acid solution of unknown concentration is to be titrated with a standardized hydroxide solution that will be released from a buret. The buret should be rinsed with: hot distilled water distilled water at room temperature a sample of the unknown acid solution a sample of the hydroxide solution a neutral salt solution B 100 B 200 B 300 B 400 As a beaker of water is heated over a flame, the temperature increases steadily until it reaches 373K. At that point, the beaker is left on the flame, but the temperature remains at 373 as long as there is water in the beaker. This is because at 373K, the energy provided by the flame: no longer acts to increase the kinetic energy of the water molecules is completely absorbed by the glass beaker
