Solid, liquid, and gas of the same substance have different specific heat values. If 5.00 grams of this substance in the liquid phase has a specific heat value of 2.17 J/g ºC, how much energy would this need to raise the temperature from 15 ºC to 105 ºC?

answer: c. the experiment shows that the red substance experienced a chemical change.

explanation: chemical change is the change in which chemical composition of the substance changes. physical change is the change in which there is no change in chemical composition.

chemical changes are accompanied by following changes:

a) precipitate formation

b) energy is released or absorbed

c) formation of bubbles

d) change in color

as it is given that the red color has disappeared and there is production of gas, it means the red substance has undergone a chemical change.
