SOLVED:A resistance thermometer is a thermometer in which the electrical resistance changes with temperature. We are free to define temperatures measured by such a thermometer in kelvins (K) to be directly proportional to the resistance R, measured in ohms (Ω) . A certain resistance thermometer is found to have a resistance R of 90.35 Ωwhen its bulb is placed in water at the triple-point temperature (273.16 K) . What temperature is indicated by the thermometer if the bulb is placed in an enviro

SOLVED: A platinum resistance thermometer measures temperature on the assumption that the change in the electrical resistance of platinum is proportional to the change in temperature. The resistance of the platinum wire at 0Â°C is 10.4Ï€ and 10.71Ï€ at 100Â°C. Calculate the temperature when the resistance is 9.61Ï€. What will be the resistance of the wire when the temperature is 45Â°C?

SOLVED: Temperatures are often measured with electrical resistance thermometers. Suppose that the resistance of such a resistance thermometer is 131Î© when its temperature is 26.8 Â°C. The wire is then immersed in a liquid, and the resistance drops to 78.5Î©. The temperature coefficient of resistivity of the thermometer resistance is Î± = 4.00 x 10^-3 (CÂ°)^-1. What is the temperature of the liquid?

The electrical resistance in ohms of a certain thermometer varies with temperature accoding to the approximate law : R = R0 [1 = aT T0]The resistance is 101.6 Ω at the triple point of water 273.16 K, and 165.6 Ω at the normal melting point of lead 600.5 K. What is the temperature when the resistance is 123.4 Ω?

In Section 12.3 it was mentioned that temperatures are often measured with electrical resistance thermometers made of platinum wire. Suppose that the resistance of a platinum resistance thermometer is 125Ωwhen its temperature is 20.0^∘ C . The wire is then immersed in boiling chlorine, and the resistance drops to 99.6Ω. The temperature coefficient of resistivity of platinum is α=3.72 ×10^-3(C^∘)^-1 . What is the temperature of the boiling chlorine? | Numerade
