A transition between paragraphs can be a word or two (however, for example, similarly), a phrase, or a sentence. Transitions can be at the end of the first paragraph, at the beginning of the second paragraph, or in both places.
There are a number of different types of thermometers, but all have two basic elements. First, they must have a temperature sensor (mercury, dissimilar metals, etc.) capable of detecting a change of temperature. Second, they must have a means (such as a scale) of measuring the degree of change. Temporal Thermometer Accurate temperature with a gentle forehead scan.
Thermostats can be constructed in many ways and may use a variety of sensors to measure the temperature. The output of the sensor then controls the heating or cooling apparatus. A thermostat may switch on and off at temperatures either side of the setpoint. This prevents equipment damage from frequent switching.
