The temperature of a 6.0 g sample of glass change from 20 degrees celsius to 45 degrees celsius when it absorbs 550 j of heat what is this specific heat of this glass sample

The specific heat of a substance measures the energy required to raise the temperature of a one-unit-mass sample of this substance by one unit.

The question provides the following information:

The specific heat of this substance measures the energy change for a process involving:

Apply the formula

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.
