With the aid of a labelled diagram, describe how the room temperature can be measured using uncalibrated resistance thermometer. (06marks)

• Place the resistance thermometer in a funnel with crushed ice and leave it for some time.
• Close the switch and obtain a balance point by adjusting the resistance box,
• Determine the resistance R₀ at 0⁰C from

• Transfer the resistance thermometer a beaker containing boiling water and after some time, determine resistance R₁₀₀.
• Place the resistance thermometer in water at room temperature and determine resistance R_θ.
• Temperature of the room temperature,
