Mercury.
because the molecules of oxygen only react at high temperatures
Because those are the freezing point and boiling point of mercury. Once past those, the mercury will no linger expand or contract in a proportional way to the temperature changes.
Mercury freezes at -38.83 °C (-37.89 °F) so it can only be used at temperatures higher than this.
The liquid metal in many thermometer is mercury (Hg).
only in a thermometer
It's used in thermometers because it has high coefficient of expansion. also it's the only metal in a liquid state.
The mercury in the thermometer's tube expands and contracts due to the surrounding temperature. As the mercury is inside a narrow tube, it can only expand upwards, and contract downwards.
it is mercury. its actually a liquid at room temperature.
Mercury is rich in metals because only metallic grains could survive the high temperatures so near the Sun.
A clinical thermometer - is designed to measure typical human temperatures. The 'normal' temperature of a human is 37 C (98.4 F). There's no point in using a thermometer that can measure a huge range - when human temperatures fall within a very narrow range.
The Mercury expands with temperature. Since expansion is linear over the normal range of a mercury-driven thermometer, the level of mercury within a little glass tube indicates the current temperature of the thermometer's immediate environment.
To measure temperatures to an accuracy greater than only whole degrees.
A clinical thermometer can only measure human body temperatures since it can measure no less than 35 degrees celcius and no more than 42 degrees celcius. An ordinary thermometer can measure and object or substance at any temperature.

Actually, you should NOT. Mercury is very toxic.
