Question

Aluminum is used for making cooking utensils. which of the following propertis of aluminium are responsible for the same ?
(i) Good thermal conductivity ctrical conductivity
(ii) Good electrical conductivity
(iii) Ductillity
(iv) High melting point

• A. (i) and (ii)
• B. (i) and (iii)
• C. (ii) and (iii)
• D. (i) and (iv)

Answer 1

The correct option is D (i) and (iv)

Aluminium is used for making cooking utensils,the properties used.

(1)Good thermal conductivity & electrical conductivity.

Thermal conductivity good implies laser cooking and saves time.

(ii)Malleable property chelps it to easily shape into utensils.

(iii)High melting point would ensure utensils don't melt on cooking temperature.
