What is platinum thermometer?

A platinum thermometer is a type of resistance thermometer that uses a platinum element as the temperature-sensing material. Platinum is often chosen for its high accuracy and stability over a wide range of temperatures, making platinum thermometers suitable for precision temperature measurement applications.


What is the function of compensating leads in the platinum resistance thermometer?

Compensating leads help to reduce errors in temperature measurement by minimizing the impact of lead resistance on the overall measurement. They are made of the same material as the sensor to maintain consistency in resistance, ensuring accurate temperature readings.


Thermometer use to measure temperature above 1250 celsius?

A thermocouple or a pyrometer is commonly used to measure temperatures above 1250 degrees Celsius. These devices are designed to withstand high temperatures and provide accurate temperature readings in such extreme conditions. It is important to select the appropriate type of thermometer that can handle the desired temperature range for accurate results.


What are the industrial used of platinum?

Temperature can be measured by what?

Temperature is measured by a liquid in glass thermometer in most cases. Other instruments such as thermocouples, resistance or digital thermometers are used for more extreme conditions.


Does platinum dissolve in nitric acid?

Platinum does not dissolve in nitric acid, which is why it is commonly used in jewelry and other applications that require resistance to corrosion.


Why you use rheostat of 15ohm resistance in melde's experiment?

A rheostat with a 15 ohm resistance is used in Melde's experiment to control the amount of current passing through the system. By adjusting the resistance of the rheostat, the frequency of vibration of the standing wave on the string can be varied. This allows for the different modes of vibration to be studied in the experiment.
