Let's match each word with its correct description from the options provided:
Flexible - The correct description is 'Easy to bend or deform without breaking.' Flexible materials can bend or stretch without shattering. An example could be rubber, which can be bent and twisted without breaking.
Brittle - The correct description is 'Will break easily if bent / deformed.' Brittle materials, such as glass, tend to crack or shatter rather than deform when stressed.
Porous - The correct description is 'Allows gas or liquid to pass through.' Porous materials have small holes or spaces, allowing substances like air or water to pass through. A common example is a sponge.
Buoyant - The correct description is 'Will float in water.' A buoyant object has the ability to float on the surface of a liquid due to its density being lower than the liquid. Cork is a good example of a buoyant material.
Transparent - The correct description is 'Allows light to pass through.' Transparent materials, like clear glass or clean water, let light pass through them so that objects can be seen clearly on the other side.
By understanding these properties, we can predict how different materials will behave in different conditions and applications.
