A liquid, X, was allowed to cool in air. The temperature was measured every five secds. The graph below represents the cooling curve of X. (a) What is the melting point of X?
(b) What is the room temperature? Explain your answer.
(c) X has a boiling point of 128°C. Explain, in terms of the kinetic particle theory, what happens to the particles of X as it is heated from 100°C to 150°C.
(d) In which parts of the graph is energy being given out to the surroundings?​

- aluminum and copper chloride.

- the chloride ion to separate the aluminum from the oxygen so that the aluminum can react with the copper ions (and the water molecules).

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

the dependant variable is spilled water

the independent is the heat

with this one i know the answer in craters one reason i looked it up and i learned about it there is my evidence
