we use mercury lamp instead of ordinary lamp because ordinary lamp has many wavelengths when mercury lamp has single wavelength so in constant deviation we use only mercury lamp.

Instead of mercury, you can use alternative materials like digital thermometers instead of mercury thermometers for temperature measurement. In addition, you can opt for alternatives such as lead-free solder in electronics and non-mercury batteries for environmental-friendly options.
A mercury cell maintains a constant voltage throughout its life because it has a relatively constant internal resistance, which helps to stabilize the voltage output. The chemistry of the cell ensures that the voltage remains consistent as it discharges.

The state of mercury at ordinary temperature and pressure is liquid, but it becomes solid at -39oC and becomes vapour at 357oC.

The distance form Mercury to the Sun is not constant because Mercury's orbit is not a perfect circle. The average distance is 35,980,000 miles.
One constant in a mercury-in-glass thermometer is the volume of mercury in the bulb, which expands and contracts with temperature changes. Another constant is the linear expansion coefficient of the glass tube, which allows for an accurate measurement of temperature based on the change in volume of the mercury.
Mercury is the only metal that is in liquid state under ordinary conditions, specifically at room temperature.

Most modern thermometers no longer use mercury due to its toxicity. Instead, digital thermometers, infrared thermometers, and other types of thermometer technology that do not contain mercury are widely available and recommended for safer use.
