Q1. A centigrade and a Fahrenheit thermometer are dipped in boiling water. The water temperature is lowered until the Fahrenheit thermometer registers 140°. What is the fall in temperature as registered by the Centigrade thermometer

•  30°
•  40°
•  60°
•  80°

Q2. At what temperature the centigrade (Celsius) and Fahrenheit, readings are the same

•  – 40°
•  + 40°
•  + 36.6°
•  – 37°

Q3. Standardisation of thermometers is obtained with

•  Jolly's thermometer
•  Platinum resistance thermometer
•  Thermocouple thermometer
•  Gas thermometer

Q4. The gas thermometers are more sensitive than liquid thermometers because

•  Gases expand more than liquids
•  Gases are easily obtained
•  Gases are much lighter
•  Gases do not easily change their states

Q5. Mercury thermometers can be used to measure temperatures upto

•  100°C
•  212°C
•  360°C
•  500°C

Q6. A constant volume gas thermometer shows pressure reading of 50 cm and 90 cm of mercury at 0°C and 100°C respectively. When the pressure reading is 60 cm of mercury., the temperature is

•  25°C
•  40°C
•  15°C
•  12.5°C

Q7. The relation that converts temperature in Celsius scale to temperature in Fahrenheit scale is

•  t°F = 5/9(t°C - 32)
•  t°F = 5/9(t°C + 32)
•  t°F = 9/5(t°C + 32)
•  t°F = 9/5(t°C + 32)

Q8. A temperature difference of 5°C on Celsius scale corresponds to the following temperature difference in the Fahrenheit scale

•  9°
•  41°
•  2.8°
•  15°

Q9. Mercury boils at 367°C. However, mercury thermometers are made such that they can measure temperature up to 500°C. This is done by

•  Maintaining vacuum above mercury column in the stem of the thermometer
•  Filling nitrogen gas at high pressure above the mercury column
•  Filling nitrogen gas at low pressure above the mercury column
•  Filling oxygen gas at high pressure above the mercury column
