The region around a magnet where the magnetic force is exerted is known as magnetic field<span>. Magnetic field is the area around a magnet, a magnetic object or an electric charge in which magnetic force is exerted. Magnetic fields are created by moving electric charge. Magnetic field is measured by its strength and by the direction it points. The strongest external magnetic fields are near the poles. A magnetic north pole will attract the south pole of another magnet, and repel a north pole. In a bar magnet the magnetic field lines can be traced out with the use of a compass.</span>
When gasses are heated they emit only certain wavelengths of light (an emission line spectrum). Different gasses emit different wavelengths. A cool object (gas or solid) can absorb some of the light passing through it. The temperature of an object is a measure of how much energy its atoms have.

Answer:
Explanation:
Carbon disulphide is the liquid that can be used to separate iron fillings and sulphur powder.
When carbon disulphide is poured into the dish, the sulphur powder gets easily dissolved in the carbon disulfide. The iron fillings are left to settle on the bottom of the dish.
The iron fillings can get seperated through filtration. When the mixture of sulphur powder and carbon disulphide gets completely evaporated, the sulphur powder is left over.
Answer:
D metallic
Explanation:
The chemical bonding which rises from electrostatic attractive force between the conduction electrons and the positively charged metal ions is called metallic bonding.
<u>It is sharing of the free electrons among the structure of the positively charged ions which are known as cations.
</u>
<u>In this type of bonding, these free electrons freely move in the crystal mattice of the metal. </u>
The bonding accounts for properties of metals, such as ductility, strength, electrical and thermal conductivity and resistivity and luster.
