What temperature is twice as cold as zero degree Celsius?
It is known that the temperature of an object today is zero degree Celsius. What is the temperature of the object tomorrow if it is twice as cold as it is today?
If the temperature of the object increases so that it is twice higher than zero degree Celcius, what is the temperature then? Can we really call it twice as warm?
