Water-bath canning refers to hot water canning and uses a large kettle of boiling water. Filled jars are submerged in the water and heated to an internal temperature of 212°C for a specific period of time. This method is utilized for processing high-acid foods, such as fruit, items made from fruit, pickles, pickled food, and tomatoes. •
A little experimentation may be necessary to determine if evaporative cooling and/or ice water cooling provides the proper temperature range for your brewing environment. A self adhesive temperature strip placed on the outside of a fermenting vessel above the level of an ice water bath can provide a simple and convenient means of monitoring .
constant temperature oil bath. 10 ml. of a stock protein solution were placed in a similar tube in the bath. If the temperature was low enough, no appreciable change occurred in the stock solution and it was allowed to come to bath temperature. To start the reaction, 10 ml. of the buffer
Lab freezing bath temperatures. Freezing mixtures in the lab are often made from a mixture of either liquid nitrogen or dry ice with a solvent. If using liquid nitrogen this forms a slurry. The viscosity of this slurry is dependent on the solvent or mixture of solvents used.

The first experiment conducted was the hot experiment. To test how well amylase would break down starch in a very hot temperature, 100ml of water was put into a beaker with a Celsius thermometer and heated until boiling (100 degrees Celsius) using the electric hot plate set on high.
If you immerse the cylinder you see in the first figure in a heat bath, what would happen? The heat, Q, would flow into the apparatus, and because the temperature of the gas stays constant, all that heat would become work done by the system. Say that you have a mole of helium to play around with on a rainy day of temperature 20 degrees Celsius, and for fun you decide to expand it from V i = 0 .
