A thermometer reading `80^@F` is taken outside. Five minutes later the thermometer reads `60^@F` . After another 5 minutes the thermometer reads `50^@F` . What is the temperature outside?

The upper and lower fixed points of a fualty thermometer are 5^(@)C and 105^(@)C . If the thermometer reads 25^(@)C , what is the actual temperature?

A centigrade and a Fehrenheit thermometer are dipped in boiling water. The water temperature is lowered until the Fehrenheit thermometer registers 140^(@)F . What is the fall in temperature as register by the centigrade thermometer

A gas thermometer is used as a standard thermometer for measurement of temperature. When the gas container of the thermometer is immersed in water at its triple point 273.16K , the pressure in the gas thermometer reads 3.0xx10^4N//m^2 . When the gas container of the same thermometer is immersed in another system, the gas pressure reads 3.5xx10^4N//m^2 . The temperature of this system is therefore __________ .^@C .

A faulty thermometer reads 5^@ C melting ice and 99^@ C in steam. Find the correct temperature in ^@ C when this faulty thermometer reads 52^@ C .

The readings of a bath on Celsius and Fahrenheit thermometers are in the ratio 2 :5. The temperature of the bath is

An arbitrary scale has the ice point at -20^(@) and the steam point at 180^(@) . When the thermometer reads 5^(@) , then find the read of centigrade thermometer.

Is the thermometer reading of the temperature of air (in shade) the same as the temperature of sand or water? What do you think is the reason for this? And why does the temperature have to be measured in the shade?
