Question

the melting point of gallium metal is 29.76°C If a piece of gallium is sliced into three parts, the melting point will be:

A. higher than 29.76°C
B. 29.76°C
C. lower than 29.76°C

​

Answer 1

Answer:

B. 29.76°C

Explanation:

The melting point of each parts will be 29.76°C.

Melting point is the temperature at which a substance changes state from solid to liquid.

This quantity is an intensive property of matter and it does not depend on the quantity of matter therein.

• All given mass of gallium will melt at 29.76°C
• With the mass present and the heat supplied, it can take different time but once the temperature of 29.76°C is attained, gallium will begin to melt.
