Question

The base of an electric press is made thick and heavy because:

विकल्प

• The heavy base can store large amount of heat.

• The heavy base will not allow the temperature to go beyond safe limits

• In case of electric supply stops the press will keep hot for some time.

• All of these

Answer 1

All of these

Explanation:

A thick, heavy base has a large heat capacity, so it stores a lot of heat, keeps the temperature within safe limits, and stays hot for some time even after the supply stops. Hence, 'all of these' is correct.
