A centimeter scale is fixed next to an unmarked mercury-in-glass thermometer. The ice point and steam point are marked.

What is the temperature shown on the thermometer?

A thermometer with no scale is taped to a ruler as shown. When placed in steam, the mercury level rises to 22 cm. When placed in pure melting ice, the mercury level falls to 2 cm.

Which temperature is shown by the mercury level in the diagram?

1. A platinum resistance thermometer has resistances of 5.25 Ω and 9.25 Ω at 0⁰C and 100⁰C respectively. Find the temperature in celcius when the resistance is 8.25 Ω.

The ice and steam points on a thermometer correspond to Q and 80 mm respectively. A temperature of 60⁰C corresponds to 52 mm on the thermometer. Find the value of Q.

A thermometer with an arbitrary scale Y registers -50⁰Y at the lower fixed point and +70⁰Y at the upper fixed point. Find the celcius temperature corresponding to 30⁰Y.
