1665183.6J
Explanation:
Given parameters:
Mass of Gold = 12400g
Initial temperature = 23°C
Final temperature = 1064°C
Unknown:
Energy required to melt = ?
Solution:
The amount of heat required to cause this temperature change to heat the gold bar is given as;
H = m c Ф
m is the mass of gold bar
c is the specific heat capacity of gold
Ф is the heat change
Specific heat capacity of gold = 0.129J/g°C
H = m c (Ф₂ - Ф₁)
H = 12400 x 0.129 x (1064 - 23) = 1665183.6J

Hi there!
Typically volcanoes are found alongside tectonic plate boundaries and in that sense could be considered a pattern. One of the most famous is 'The Ring of Fire' which is a ring of volcanoes in the pacific ocean along the pacific plate boundary.
Gravity affects weight of an object
Its weight reduces as it moves away from the center as gravity is strongest near the core and reduces as you move away
Hope this helps C:
