Explanation

Boiling point of Sulfur is 444.7°C.

Melting point of Sulfur is 112.8°C.

Explanation

This is called nuclear fusion.

It takes four hydrogen atoms to fuse into each helium atom. During the process some of the mass is converted into energy

Explanation

Explanation

The main reason for adding helium to the breathing mixture is to make the nitrogen-oxygen ratio lower than the air ratio so that the gas mixture can breathe safely in the deep sea. Lower levels of nitrogen are needed to reduce deep gas nitrogen anesthesia and other physiological effects.

• Ozone protects the Earth from harmful ultraviolet (UV) rays from the solar. with out the Ozone layer inside the atmosphere, existence on the earth could be very hard. plant life cannot live and grow in heavy ultraviolet radiation, nor can the planktons that serve as food for most of the sea existence.
• With a weakening of the Ozone Layer defend, human beings would be greater at risk of skin cancer, cataracts and impaired immune systems.
• Ozone can both shield and damage the Earth — it all depends on in which it is living. for example, if Ozone is present in the stratosphere of the ecosystem, it's going to act as a guard.
• however, if it is in the troposphere (about 10 km from the Earth's floor), Ozone is harmful. it's miles a pollutant that could purpose damage to lung tissues and plants. hence, an upset inside the ozone balance can have extreme outcomes

Explanation

Coal tar is a thick dark liquid which is a by-product of the production of coke and coal gas from coal.

It has both medical and industrial uses.

Explanation

Oxygen is the chemical element with the symbol O and atomic number 8. 

Explanation

the kinetic energy of an object is the energy that it possesses due to its motion.

It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity.

Applying a force requires us to do work.

Kinetic energy is directly proportional to the mass of the object and to the square of its velocity: K.E. = 1/2 m v2

Explanation

This relationship is called Boyle's Law and makes up part of the ideal gas law.

When the volume of a gas shrinks, the gas molecules have less space to move around and so they hit their container.
