Question

Give an example of a metal which
(1) is a liquid at room temperature.
(ii) can be easily cut with a knife.
(111) is the best conductor of heat.
(iv) is a poor conductor of heat.​

Answer 1

Answer:

1.Metals like mercury, gallium etc are almost liquid in the average room temperature. Because these metals have a small amount of melting point.

2.Lithium, potassium are all soft metals that are easily cut with a scalpel or knife. The freshly cut surface is a shiny, silver colour, but this tarnishes quickly to a dull grey as the metal reacts with oxygen and water in the air.
