Answer: The gold will become liquid at 1064°C.
Step-by-step explanation:
Melting point is defined as the temperature at which solid state starts to change its phase into liquid state at constant temperature.

Boiling point is defined as the temperature at which liquid state starts starts to change its phase into gaseous state at constant temperature.

For the given gold substance:
Melting point is given as 1064°C and boiling point is given as 2700°C.
This substance will be in liquid state after its melting point which is 1064°C.
Hence, the gold will become liquid at 1064°C.
