Question

Which of the following properties of a substance cannot be changed by application of force?
A. Shape
B. Size
C. Elasticity
D. Reactivity with water

Answer 1

Hint:To answer this question, we first need to understand what force is. In physics, a force is any interaction that, while unopposed, causes an object to change its velocity. An object with mass can change its velocity, or accelerate, as a result of a force. Intuitively, force can be described as a push or a pull. A force is a vector quantity since it has both magnitude and direction.

Complete answer:
Physical Properties of a substance: A physical property is a quality of matter that is independent of its chemical composition. Density, color, hardness, melting and boiling points, and electrical conductivity are all examples of physical qualities. Some physical attributes, such as density and hue, can be measured without affecting the matter's physical state. Other physical attributes, such as iron's melting temperature or water's freezing temperature, can only be noticed when matter experiences a physical change.

Chemical Properties of a substance: Chemical properties are characteristics that can only be measured or observed when matter transforms into a different type of matter.Reactivity, flammability, and the ability to rust are among them. The ability of matter to react chemically with other substances is known as reactivity.

Force simply affects the physical state of a substance, not its chemical condition (properties). Because a substance's reactivity with water is a chemical property, it will not be affected by the application of force. So, we can conclude that chemical properties can’t be changed by applying force.

Hence, the final answer is option D.

Note: Substance is defined as a material with distinct qualities and makeup. A substance is a pure compound or element. Water is a pure material made up of hydrogen and oxygen atoms. A homogeneous substance is one that is free of impurities. Elements and compounds are the two kinds of pure substances. Elements are built up of atoms of the same sort. Consider the metals gold and silver.
