When carrying out experiment in the laboratory to investigate physical changes, absolute measurement is usually not needed. For instance, one can just take a little sample of sodium chloride and dissolve it in water to demonstrate physical change. But for other experiments, such as the measurement of the catalase enzyme activity in a liver tissue. Careful measurements have to be made when preparing the chemicals that will be used in the experiment.
Physical properties. Neodymium is a soft, malleable metal. Malleable means capable of being hammered into thin sheets. It can be cut and shaped fairly easily. It has a melting point of 1,024°C (1,875°F) and a boiling point of about 3,030°C (5,490°F).

Hello!
The light from the sun hits one side of the moon and doesn’t hit from the other side. So that’s how we view it on earth
Hope this helps! Correct me if I’m wrong :)
