  • 2. 
    The sensitivity of a liquid-in-glass thermometer depends on the volume of liquid used and the diameter of the bore of the thermometer. What changes will produce the greatest increase in sensitivity?   Volume of liquid Bore diameter A B C D Decreases Decreases Increases Increases Decreases Increases Decreases Increases

  • 3. 
    A thermocouple thermometer uses a voltmeter to measure the e.m.f. generated between two junctions. The junctions are at temperatures t1 and t2. To calibrate the thermometer, fixed points are needed.What are the values of t1 and t2 when the thermometer is calibrated at the steam point? t1t2ABCD0 0C0 0C25 0C25 0C0 0C100 0C0 0C125 0C
