Temperature and Thermometers starts at 7 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Temperature and Thermometers.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 11
A laboratory experiment requires a temperature of 350 K. What is this temperature in Celsius?
A thermocouple produces a voltage of 2 mV when the temperature difference between its junctions is 50°C. What is the sensitivity of the thermocouple in mV/°C?
Convert 25°C to Kelvin.
Convert 98.6°F (normal human body temperature) to Celsius. (Use the formula: °C = (°F - 32) × 5/9)
Describe how a thermocouple thermometer works.
Describe the process of calibrating a thermometer.
A scientist needs to measure the temperature of molten metal. Which thermometer should they use?
(1) Mercury thermometer
(2) Alcohol thermometer
(3) Thermocouple
(4) Clinical thermometer
A scientist is using a gas thermometer to measure the temperature of a substance. The pressure of the gas at 0°C is 80 kPa, and at the temperature of the substance, it is 120 kPa. What is the temperature of the substance in Celsius? (Assume ideal gas behavior.)

A clinical thermometer typically measures temperatures in the range of ________ °C to ________ °C.
A resistance thermometer uses the change in ________ of a metal wire to measure temperature.
The boiling point of water at standard atmospheric pressure is ________ K.
The temperature at which the molecules of a substance have minimum possible energy is called ________.
Is it possible for two objects to have the same temperature but different amounts of heat?
True or False: Temperature is a measure of the average kinetic energy of the particles in a substance.
True or False: The Fahrenheit scale has 180 equal divisions between the freezing and boiling points of water.
True or False: The triple point of water is used to define the Kelvin scale.
