the element 'X' which is available inthe liquid state in the liquid state and also used in the clinical thermometer . What is X'
Answers
Explanation:
The melting point of gallium is 30°C and boiling point is 2240°C. Thus, the element exists in liquid state for a wide range of temperature.
Answer:
The element 'X' used in the clinical thermometer is Mercury, Hg
Explanation:
Mercury is the only metal that is in liquid state. It is used in clinical thermometer as: -
1. Its boiling point is extremely high. At 674°F (78.37°C), mercury begins to boil.
2. Although Mercury's coefficient of expansion is high, it is not excessively so. Mercury also has a high coefficient of expansion. This implies that mercury in a thermometer will react when heated. Before the mercury begins to descend once more, you will have time to check your thermometer and read the reading it provides.
3. Mercury is a desirable contender since it is the only metal that is a liquid at ambient temperature.
4. It can measure high temperatures very accurately and is also inexpensive to buy.
5. In addition, a mercury thermometer can be used without an external power source like a battery or electricity. Mercury is appealing because it can sustain itself.
