I suppose that emerald is decomposed before boiling.
Melting points and boiling points are phyical constants which means specific compounds have specific melting/boiling points. Therefore you can identify a substance if you determine the mp/bp. Also you measure the purity of a mixture using melting point tests.
You might make it explode or make some deadly gas. Research what you're doing before you perform an experiment.
It's best to put it in RIGHT BEFORE it's boiling. Time it out right so that when the water is just beginning to bubble, drop it in.
Water.
I am not sure but may be it is because none of the substances have a fixed boiling point. The substance starts changing its state from liquid to gas before the mentioned boiling point . For example Boiling point of H2O is 100.but it change it changes its state before it.Therefore there are boiling range not boiling point.
The boiling point is the temperature at which a liquid changes to gas or starts to vaporize. The boiling point of liquids depends on the specific liquid or fluid. For example, water boils at 100 degrees Celsius, and olive oil's boiling point is 300 degrees Celsius.
They are scared because many changes are about to happen during puberty. Also, there is the fear of the unknown

The motivation is to avoid uncontrolled boiling and splashing.

In most cases it changes immediately. The laws do vary some between states, but both parties reap the benefits of the properties.
you measure the water before boiling. after boiling would be more tricky.
options (A) Boiling point (b) Colour (C) Smell (D) Solubility in water.
Water - or other liquids - will evaporate at practically any temperature. Boiling is defined as the temperature at which the partial vapor pressure is equal to the atmospheric pressure. In practical terms, it means that the boiling water (or other liquid) can't get any hotter assuming the pressure doesn't change. You'll also see lots of bubbles rising from the boiling liquid (but before it is boiling, there will also be a few bubbles).
