Fractional Distillation is the answer
It’s mass number would be 5 as it’s the protons and the neutrons added together
<h2>Answer:</h2>
In both glasses have juices of same mass. But the temperature is different due to which the kinetic energy of molecules in both glasses is different.
As kinetic energy is directly proportional to temperature.
To make the kinetic energy of the molecules equal she should:
- Heat one glass of 25°C to 40°C.
or
- Cool the juice of 40°C to 25°C
Each period in the periodic table corresponds to a principal energy level
