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

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.

answer

fusion: the energy source of stars. the energy released from the collapse of the gas into a protostar causes the center of the protostar to become extremely hot. when the core is hot enough, nuclear fusion commences. fusion is the process where two hydrogen atoms combine to form a helium atom, releasing energy.

hope it

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z
