What is Temperature? Temperature may be defined as the condition of a body which determines the transfer of heat to or from other bodies. Use thermometers to determine temperature

Temperature: degree Celsius (°C)

Thermometer A Thermometer B is calibrated such that the smallest division represents one Celsius degree. When reading this thermometer we can see that the temperature of the sample was for certain greater than 21 o C and less than 22 o C Thermometer A is calibrated such that the smallest division shown represents two Celsius degrees. The temperature of the sample was for certain greater than 18°C and less than 20°C Thermometer B

What is the temperature reading of the thermometer and how many significant figures are allowed for this reading?
