Question

Define the following and give two examples for each.
(a) Immiscible liquids
(b) Conductors
(c ) Opaque objects​

Answer 1

Answer:

(a).Immiscible liquids are those which won't mix to give a single phase. Oil and water are examples of immiscible liquids - one floats on top of the other. It explains the background to steam distillation and looks at a simple way of carrying this out.

(b).Conductors are the materials that are good conductors of thermal energy whereas Insulators poor conductors of thermal energy. Conductors of heat: copper, iron. Insulators of heat: plastic, rubber.

(c).An opaque object is something that allows no light through it. Concrete, wood, and metal are some examples of opaque materials. Some materials can be opaque to light, but not to other types of electromagnetic waves.

Answer 2

Explanation:

( a)Immiscible liquids are those which won't mix to give a single phase. Oil and waterare examples of immiscible liquids - one floats on top of the other. It explains the background to steam distillation and looks at a simple way of carrying this out.

(b)Copper, Brass, Steel, Gold, and Aluminium are good conductors of electricity. We use them in electric circuits and systems in the form of wires. Mercury is an excellent liquid conductor. Thus, this material finds use in many instruments.

(c)Opaque objects block light from traveling through them. Most of the light is either reflected by the object or absorbed and converted to thermal energy. Materials such as wood, stone, and metals are opaque to visible light.
