What is Celsius scale?

If the difference between two temperatures in Kelvin scale be DeltaT and that in Celsius scale be Deltat , then-

IF heated to 35^@C at constant pressure, the volume of gas increases from 5L to 0^@C by 640 cm^3 . What should be the value of absolute zero for this gas in Celsius scale?

At constant pressure if the temperature of 5L of a gas is increased from 0^@C to 35^@C the volume increases by 640 cm^3 From this data,determine the value of absolute zero temperature is Celsius scale.

If the coefficient of linear expansion of iron is 0.0000067^(@)F^(-1) , then what is its value in celsius scale?

What is the relation between kelvih scale and Celsius scale?

It is given that the specific heat of water in cal.g^(-1) unit is s=0.6t^(2) , where t is the temperature in Celsius scale. what amount of heat is required to raise the temperature of 10g water from 0^(@)C to 10^(@)C ?

One thermometer is graduated in the Celsius scale and another in the Fahrenheit scale. Both of them are used alternately to measure the temperatures of two objects. In both the cases, the differences in reading of the two thermometers are observed to be 20 degree. If the temperature of the objects are different, find their values in the Celsius scale.

At what temperature the reading of Fahrenheit will be twice Celsisu scale.?
