Answer: i think it is chemical change because of such temperature change outcome in a different form probably proves that it is a chemical change.
Explanation:
Calcium carbonate is strongly heated until it undergoes thermal decomposition to form calcium oxide and carbon dioxide. The calcium oxide (slaked lime) is dissolved in water to form calcium hydroxide (lime water). Bubbling carbon dioxide through this forms a milky suspension of calcium carbonate.
