Video transcript. Voiceover: Three years prior to the making of this painting, Pollock was working on a small easel painting. He had struggled on it for a while, and he decided to take that painting off the easel, place it on the floor, and then pour some paint on the surface to finish it.
Calibrating Thermometers. Calibrating a thermometer is actually a very simple process. It may be necessary to do from. time to time to ensure accuracy. The following instructions should help you. Dial Thermometers. By placing the stem of the thermometer in an ice water bath you can check the lower. temperature on the scale. Alternately, by placing the stem of the thermometer in boiling water. you can check the boiling temperature. The ice bath should be 32ÂºF (0Â°C). Use a glass bowl mostly filled with crushed ice and water; a.
Also, they are often much more sensitive than primary ones. For secondary thermometers knowledge of the measured property is not sufficient to allow direct calculation of temperature. They have to be calibrated against a primary thermometer at least at one temperature or at a number of fixed temperatures.hile an individual thermometer is able to measure degrees of hotness, the readings on two thermometers cannot be compared unless they conform to an agreed scale. Today there is an absolute thermodynamic temperature scale.
