Question

A certain resistance thermometer read 14.5 ohms in pure melting ice and 18.5 ohms in steam at standard atmospheric pressure what will be its resiatance at room temperature 27.0c

Answer 1

The resistance of the thermometer at room temperature is 15.04 ohms.

What is a resistance thermometer?

A resistance thermometer is a type of thermometer that measures temperature through a change in resistance.

To calculate the resistance of the thermometer at room temperature, we use the formula below.

Formula:

• 100/27 = 2/(x-14.5)..............Eqquation 1

Where:

• x = Resistance of the thermometer at room temperature

Make x the subject of the equation

• x = [(27×2)/100]+14.5
• x = (54/100)+14.5
• x = 0.54+14.5
• x = 15.04 ohms.

Hence, The resistance of the thermometer at room temperature is 15.04 ohms.
