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.
A typical thermometer is a calibrated, or numbered, glass tube that contains mercury. The silver mercury in the tube rises, or expands, when warmth of an object increases. The mercury falls when warmth of an object decreases. The calibrated scale on the tube of the thermometer allows us to read the temperature.
