Who invented platinum thermometer?
The platinum thermometer was invented by the German physicist Carl Wunderlich in the 19th century. He utilized the unique properties of platinum, such as its resistance to corrosion and consistent electrical resistance, to create a highly accurate thermometer.
Why platinum is used in platinum resistance thermometer experiment?
Platinum resistance thermometer requires a small current to pass through it to determine its resistance at different temperatures. Platinum has a linear resistance-temperature relationship; we can use this method to find the resistance at different temperatures.
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.
Is rhenium a platinum metal?
Yes, rhenium is a platinum group metal, commonly associated with platinum, palladium, and rhodium. It shares similar properties with these metals, such as high melting points and resistance to corrosion.
How can you identify platinum?
Platinum can be identified by its silvery-white color, high density, and resistance to corrosion and oxidation. It also has a high melting point and is often marked with a "Pt" stamp indicating its platinum composition.
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.

How does a platinum resistance thermometer work?
They are slowly replacing the use of thermocouples in many industrial applications below 600 °C, due to higher accuracy and repeatability.Common RTD sensing elements constructed of platinum copper or nickel have a unique, and repeatable and predictable resistance versus temperature relationship (R vs T) and operating temperature range. The R vs T relationship is defined as the amount of resistance change of the sensor per degree of temperature change.
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.
Does a Kelvin thermometer contain mercury or alcohol?
There is no mechanical difference between a kelvin thermometer and any other kind so I think it would be the same as other thermometers i.e. Alcohol (because it is not as dangerous as mercury)

What are the industrial used of platinum?
These metals are used as emission catalysts for automobiles and in electronics and glass applications. Platinum is highly valued for its corrosion resistance and catalytic activity.
Is platinum a metal or non-metals or metalloid?
Platinum is a metal. It is a rare and precious metal known for its resistance to corrosion and high value in various industries such as jewelry, electronics, and automotive.
What is stronger tungsten or platinum?
Tungsten is stronger than platinum. Tungsten has a higher tensile strength and hardness compared to platinum, making it more durable and resistant to wear and tear. Platinum, on the other hand, is valued for its high corrosion resistance and rarity.
