Answer:
Gas to liquid
Explanation:
As the atoms temperature decreases, the kinetic energy of the atom decreases. Besides if it is turning to solid the atoms will be fixed position,they wont pass each other. So it here is forming to become a liquid
Matter
Because the force and it hard
Answer:
It is greater than -600kJ/mol and the amount of energy required to break bonds is greater than the amount of energy released in forming bonds.
Explanation:
In an endothermic reaction, the reaction requires a determined amount of energy to occurs.
The reaction of the problem has H = -600kJ/mol. The reaction is endothermic and the energy that the reaction needs is absorbed by the reactants. That means, the energy of products:
Is greater than -600kJ/mol and the amount of energy required to break bonds is greater than the amount of energy released in forming bonds.
7200sec÷60sec in a minute÷60minutes in an hour=2hours. 150km÷ 2 hours= 75 km/hour
