n the sudden occurrence of a violent discharge of steam and volcanic material. a volcanic eruption in which a stream of gas and ash is violently ejected to a height of several miles. the sudden giving off of energy.
Most people think of a normal body temperature as an oral temperature of 98.6Â°F (37Â°C) .This is an average of normal body temperatures. Your temperature may actually be 1Â°F (0.6Â°C) or more above or below 98.6Â°F (37Â°C) .he body is very good at keeping its temperature within a narrow, safe range in spite of large variations in temperatures outside the body. When you are too hot, the blood vessels in your skin expand (dilate) to carry the excess heat to your skin's surface.
Therefore, an oral temperature of 37.3 Â°C (99.1 Â°F) would, strictly speaking, be a normal, healthy temperature in the afternoon but not in the early morning. An individual's body temperature typically changes by about 0.5 Â°C (0.9 Â°F) between its highest and lowest points each day.ormal human body temperature varies slightly from person to person and by the time of day. Consequently, each type of measurement has a range of normal temperatures. The range for normal human body temperatures, taken orally, is 7002309950000000000â 36.8Â±0.5 Â°C (7002309927777777777â 98.2Â±0.9 Â°F).
