A platinum resistance thermometer has a resistance of $20 \Omega$ at $0^\circ C$ and $25 \Omega$ at $100^\circ C$. If its resistance is measured to be $24 \Omega$ when placed in a hot bath, what is the temperature of the bath, assuming a linear relationship between resistance and temperature?

Two temperature scales A and B are related by $\frac{{A - 42}}{{110}}$ = $\frac{{B - 72}}{{220}}$. At which temperature two scales have the same reading?

A platinum resistance thermometer reads ${0^0}C$ when its resistance is 80 $\Omega$ and ${100^0}C$ when its resistance is 90$\Omega$. Find the temperature at the platinum scale at which the resistance is 86$\Omega$

Which substance is commonly used in laboratory thermometers?

The correct value of ${0^0}C$ on the Kelvin scale is

A pyrometer is calibrated to measure temperatures in the range of 500°C to 2500°C. Which of the following is NOT a valid reason for choosing a pyrometer over a thermocouple in this temperature range?

Oxygen boils at $\left( { - {{183}^ \circ }C} \right).$ The temperature on the Fahrenheit scale is

Thermoelectric thermometer is based on

The boiling point of water at standard atmospheric pressure is:

Very low temperatures are measured by

Oxygen boils at $- {183^0}C$. This temperature is approximately
