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.
Why is platinum used for jewellery?
Platinum is a naturally white metal, is more durable and dense, it does not require rhodium plating to keep it white. When it comes down to buying a platinum or white gold/gold for ring, it all depends on your taste and budget.
What is Pt in chemistry?
Platinum, Pt, it's atomic number is 78
Is platinum hard?
yes, in the sense of durability and resistance to wear and erosion, etc. Gold is durable in some ways but metallurgically softer than element no.78, the grey Stuff, Platinum. they are related. Platinum 78, Gold 79, Mercury, 80 . ( memory jog- Mercury the God of speed- mercury has the highest number of the three- 80 Miles!. that;s going some.
Metal found mixed up in a plum tin?
Platinum
What is platinum thermometer?
It is a thermometer using the platinum wire as sensor (resistance thermometer); the resistance of the wire is proportional to the temperature. This type of thermometer is used under 600 0C.

Thermometer use to measure temperature above 1250 celsius?
platinum resistance thermometer
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.
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.

Does the amount of heat produced depend on the material of the conductor?
Yes, resistance in a conductor causes energy losses due to heat. Metals such as Gold and Platinum have very low resistance but they are very expensive so Copper and Aluminium are used instead which are much more affordable but have higher resistance.

Does silver have a high or low resistance?
Silver is the best natural conductor. It has the lowest resistance of any known natural material. Your conductors - low resistance materials Silver, Copper, Gold, Aluminum, Tungsten, Brass, Iron, Platinum... Gold is sometimes favored in circuits as silver and copper both oxides.
What is the name for the instrument used to measure temperature?
Most commonly, a thermometer.Related Information:Thermometers are used to measure the increase or decrease in the temperature of a system as it gains or loses internal energy.An alcohol-in-glass thermometer has been the most common personal instrument used to measure temperature. Mercury thermometers are still around but are no longer offered for sale. Today, digital devices are available that scan the forehead or ear. Some other devices used to measure temperature are:Radiation pyrometer, for extremely high temperatures;Glass thermometer: mercury or alcohol;Thermocouple;Thermistor (thermal resistor)Bimetallic strip;Bimetallic spiral;Platinum resistance thermometer (a resistance detector);Examples:A mercury in glass thermometer uses mercury liquid contained within its glass structure to be subjected to heat.the heat causes the mercury fluid to expand along the glass tubeand the total amount of expansion can be seen as a measurealong the accurate scale of indication.This is a direct indication of the effects of temperature.A more complex method of measuring temperature could be athermocouple measuring device.A thermocouple consists of 2 dissimilar types of metal materials in the form of wires , which are joined at 1 end by weld/ fusion.this single joined end is called the hot junction. The other end of the 2 wires are then terminated at separate junctions;as in a electronic terminal block. This end of the 2 wires can be called the cold junction.For most accurate temperature measure, I think temperature sensor is the first choice.
What type of thermometer has the smallest graduation and would give the most accurate temperature reading?
A platinum resistance thermometer PRT, is the commonest thermometer with high accuracy. It may have a range from -200 C to +1 000 C, and an accuracy of up to 0.001 C provided it is installed in an appropriate measuring configuration. Similar thermometers are made from nickel (and other metals), but their cost benefit is obtained at the expense of range and accuracy. In either case, the metal must have been manufactured with the end application in mind. The standard against which high accuracy thermometers should be measured is that of the International Temperature Scale, ITS-90. This specifies a number of reference calibration points such as the triple point of various substances, and of the freezing points of others.
