Determine el cambio en la energía interna en el proceso de fusión de un cubo de hielo de 12 g y cuya temperatura inicial es 0˚C

At an oceanside nuclear power plant, seawater is used as part of the cooling system. this raises the temperature of the water that is discharged back into the ocean. the amount that the water temperature is raised has a uniform distribution over the interval from 10° to 25° c. what is the standard deviation of the temperature increase?
