Answer:
Yes, the statement is true.
Explanation:
Different substances requires different amount of heat because every materials has its own specific heat capacity. Heat capacity is the amount of heat required to increase its temperature by 1 degree. Different substances have different types of bonds due to which they required different amount of heat energy for its breaking.
For example, heat requirement of water is different from glucose because they are made of different substances.
A scientific theory is an explanation of an aspect of the natural world that can be repeatedly tested and verified in accordance with the scientific method, using accepted protocols of observation, measurement, and evaluation of results. Where possible, theories are tested under controlled conditions in an experiment.
Or in other words, a scientific theory is an explanation for why things work or how things happen. Scientists develop theories based on their observations of the world around them. Theories are based on ideas that can be tested. Theories are not speculative, or based on a guess.
