What does a unstable salt do?
An unstable salt is decomposed at room temperature and pressure, is easily decomposed by heating, by irradiation with different types of radiation, after the contact with other compounds or elements, become explosive after a mechanical shock etc.
How is electrical shock hazard defined?
The phrase "electrical shock hazard" means that there is a risk of electrical shock.
What acts as a shock absorber in your body?
You have the cartilages in the joints, which act as mechanical shock absorbers. But then you have other functional shock absorbers. You have arches in the foot, which act as shock absorbers. Then when you jump down, you have that spring like movement of the legs. That act as a shock absorbers.
What are the meninges of the human body?
the three layers of meninges are as follows: Outer layer(layer closet to the skull): known as the Dura Mater. Middle layer: known as the Arachnoid Inner layer(layer closest to the cerebral cortex): known as the Pia Mater ***The meninges contain cerebral spinal fluid (which is produced in the brain stem) which as a shock absorber. The meninges also provide extra support and protection for the brain.controls involuntary muscle
Why is discovery of a hole in the ozone layer a cause for concern?
The discovery of ozone hole led the scientists to search for ways to stop the depletion of ozone layer. Thus various alternated were finded to replace the substances responsible for ozone hole.
