Electrons, specifically valence electrons
Answer:
See the answer below
Explanation:
<em>Since the experiment is set out to determine the melting point of the white solid, after missing the melting point due to distraction, there are two possible solutions and both involves a repeat of the experiment.</em>
1. The first one is to allow the molten substance to solidify again and then repeat the experiment. This time around, a critical attention should be paid to be able to notice the melting point temperature once the temperature gets to 132 C.
2. The second solution would be discard the molten substance and repeat the experiment with the a new solid one. Similarly, critical attention should be paid once the temperature gets to 132 C since it is sure that the melting point lies within 132 and 138 C.
The complete question is as follows: Which statement describes the way in which energy moves between a system reacting substances in the surroundings.
A) molecule Collisions transfer thermal energy between the system and its surroundings
B) The thermal energy of the system and it’s surroundings increase
C) The potential energy of the system and it’s surroundings increases
D) molecular collisions create energy that is then released into the surroundings
Answer: The statement, molecule Collisions transfer thermal energy between the system and its surroundings describes the way in which energy moves between a system reacting substances in the surroundings.
Explanation:
When there will occur an increase in kinetic energy of molecules then there will occur more number of collisions.
When kinetic energy between these molecules tends to decrease then they will release heat energy into their surroundings.
As a result, it means that molecule collisions transfer thermal energy between the system and its surroundings.
Thus, we can conclude that the statement molecule Collisions transfer thermal energy between the system and its surroundings describes the way in which energy moves between a system reacting substances in the surroundings.
