Answer 2

Solution:

Water

(a) The temperature at which it starts changing from ice to water. The melting point of ice is 0°C.

(b) The temperature at which water starts changing from water to vapours. The boiling point of water is 100°C.

Copper

Melting point 1357.77 K (1084.62 °C, 1984.32 °F)

Boiling point 2835 K (2562 °C, 4643 °F)

ethyl alcohol

the melting point of ethyl alcohol is -114.1 °C

the boiling point of ethyl alcohol is 78.37 °C

Gold

the melting point of gold is 1,064 °C

the gold's boiling point is 2,700 °C

Silver

Melting point of Silver is 961.78°C.

Boiling point of Silver is 2162°C.

Lead

the boiling point for lead is 1,749 °C

the melting point for lead is 327.5 °C
