A compound is a substance formed when two or more elements are chemically bonded together. The property of the compound has always different from its constituents. It has a fixed composition. The constituents of the compound can be separated by chemical or electrochemical reactions. During chemical reaction heat is evolved and a new substance is formed having new characters. Here, the reaction between substance A and substance B leads to form a new substance C. So a new substance is a compound.

Answer:
When two substances A and B are powdered together in a pestle and mortar, and a large amount of heat is evolved, it indicates a chemical reaction taking place. This reaction results in the formation of a new substance C. The nature of the new substance C can be determined by considering the properties and characteristics of mixtures, compounds, and elements.
Mixture:
A mixture is a combination of two or more substances that are physically mixed together and can be separated by physical means. In a mixture, the substances retain their individual properties and do not undergo any chemical change. However, in the given scenario, when substances A and B are powdered together, a chemical reaction occurs, indicating that a mixture is not formed.
Element:
An element is a pure substance that cannot be broken down into simpler substances by chemical means. Elements are made up of only one type of atom. In the given scenario, the fact that two substances A and B are combining and reacting with each other suggests that the new substance C is not an element.
Compound:
A compound is a pure substance composed of two or more elements that are chemically combined in a fixed ratio. Compounds have properties different from the elements that make them up, and they can only be separated into their constituent elements by chemical means. When substances A and B are powdered together, and a chemical reaction occurs, resulting in the formation of a new substance C, it indicates the formation of a compound. Therefore, the nature of the new substance C is a compound.
Conclusion:
Based on the given information, when substances A and B are powdered together in a pestle and mortar, and a large amount of heat is evolved, a new substance C is formed. The nature of the new substance C is a compound.
