Answer:
Explanation:
<em>Heat</em> is a kind of energy.
The <em>kinetic theory </em>relates the heat with the movement of the particles: the more the particles move, the larger the kinetic energy of the system. The kinetic theory states that heat is the kinetic energy of the particles, atoms or molecules, in a substance, that is transferred from a substance at higher temperature to other substance at lower temperature.
Based on that principle, the kinetic theory explains the changes of phases of the substances in terms of the motion of the particles: the hotter an object the faster the particles move, the more energetic the particles are, and they occupy more space. Thus, when a solid is heated, the particles move faster and it can pass to liquid or gaseous state.
Answer:
where is the figure . u can simply add them
Answer:
D. It predicts whether or not a reaction will be spontaneous.
Explanation:
<em>What does Gibbs free energy (ΔG) predict?
.</em>
A. It predicts what the rate of the reaction will be. NO. ΔG is a thermodynamical parameter and it is not related to the kinetics of the reaction.
B. It predicts how high the activation energy is. NO. ΔG is a thermodynamical parameter and it is not related to the kinetics of the reaction.
C. It predicts if entropy will increase or decrease. NO. ΔG depends on the entropy but not the other way around.
D. It predicts whether or not a reaction will be spontaneous. YES. If ΔG < 0 the reaction is spontaneous and if ΔG > 0 the reaction is not spontaneous.
