Which of the following tools would not be used to examine an object's physical properties?

a measuring spoon, like those used in baking
a microscope to closely look at the object
a ph test strip kit
a scratching tool to establish hardness

A pH test strip kit is not used to examine an object's physical properties

Explanation:

Each and every object or element in the periodic table exhibits its own physical and chemical properties. The physical properties of an object are those which can be seen through naked eyes or which changes with respect to temperature, pressure and mass or amount of the object. While chemical properties are related to the composition of object and changes in the composition. So in the given options like measuring spoon, microscope and scratching tool, all these are used to examine physical properties like quantity, morphology or shape and hardness of the object. But the third option of usage of pH test strip is used for measuring chemical changes and mostly the acid and base nature of object. So pH test strip kit would not be used to examine an object's physical properties.

space exploration has led to the development and technological improvement of many everyday items. (if this answer is wrong i will find the right answer) : )
