What physical property makes wax good for making sculptures

Melting point.

Explanation:

The melting point of wax is very low which makes it suitable for making sculptures. It needs molding, cutting and melting of wax to make a sculpture.

such kind of modification in the wax is done by melting it at low temperature. More heat and effort is not required with wax as compared to other substances.

The wax cools down very easily after melting, it is hard when cools down and soft when heated to make the proper shape. All these properties makes the wax more suitable for making sculptures.

i think that the answer is c

answer is: nuclear fusion produces elements that are heavier than helium.

nuclei combine to form a heavier nucleus, releasing energy.  

for example, fusion of hydrogen atoms at the sun.  

this fusion nuclear reaction is in the inner core of the sun and hydrogen (atomic number 1) is conveted into helium (atomic number 2).  

the inner core is the central region of the sun and all solar energy is produced in the core by nuclear fusion.
