Answer:
Explanation:
The formula for the amount of heat absorbed by a substance is
q = mCΔT
Thus, the three factors are the
- mass
- specific heat capacity
- temperature change
The only factor that is on your list is
The shape of the substance has no effect, nor do its melting and boiling points.
Answer:
B. A chemical change occurred which caused the liquid's physical properties to change.
Explanation:
The reduction of the temperature of the system meant that the reaction absorbed heat energy from it. This shows that a chemical reaction was in progress. New products were formed, and this is proved by the change in the color to blue.
