Answer:

Melting is an endothermic reaction, while freezing is an exothermic reaction.

Explanation:

The melting process requires energy, making it endothermic.

The diagram for this would be roughly similar to _/⁻⁻ with the / part representing the melting process, and the ⁻⁻ part equivalent to liquid.

The freezing process releases energy, making it exothermic.

The diagram from this process is roughly similar to ⁻⁻\_ with the \ part representing the freezing process and the _ part equivalent to frozen.

How many copper atoms are in a pure copper statue with a mass of 142kg
Ksenya-84 [330]
142 kg in grams:

1 kg ---------- 1000 g
142 kg -------- ?

142 x 1000 / 1 => 142000 g 

Atomic mass Cu =  63.54 a.m.u

Therefore:

63.54 g ------------ 6.02x10²³ atoms
142000 g --------- ??

142000 x ( 6.02x10²³) / 63.54 =

8.54.10²⁸ / 63.54 => 1.34.10²⁷ atoms of Cu
