40000
cooling will continue when the refrigerator operates then it has freon ,if cooling stops while operating then it does not have....
Between 1 and 4oC
For what? Industrial processes in general operate from way below 0C to thousands of degrees C
Examples: wolfram (3422 0C), rhenium (3186 0C), osmium (3033 0C), tantalum (3017 0C).
A thermos flask full of hot liquid will stay hot for a time in an operating refrigerator.
Under o 0C water is a solid; between 0 0C and 100 0C is a liquid; over 100 0C is a gas.
Under o 0C water is a solid; between 0 0C and 100 0C is a liquid; over 100 0C is a gas.
Under o 0C water is a solid; between 0 0C and 100 0C is a liquid; over 100 0C is a gas.
A block of ice at 0C begins to change its temperature as it melts when it reaches 0C.
These data depends strongly on the chemical composition. For gasoline: the freezing point is from -40 0C to -60 0C For Diesel fuel: the freezing point is from -6 0C to -20 0C
