BlakeFluids can flow and take the shape of their container, while solids have a fixed shape and volume. The particles in fluids are not tightly packed and can move past each other, whereas the particles in solids are closely packed and vibrate in place. Examples of fluids include water and air, while examples of solids include wood and metal.

Why solids are not called fluids?
Solids are not called fluids because solids have a fixed shape and volume, while fluids can change shape and flow to fill the container they are in. Solids have particles that are tightly packed together and vibrate in place, whereas fluids have particles that are able to move past each other.
Why are both liquids and solids called fluids?
Both liquids and gases are considered fluids because they can flow and take the shape of their container. In a broader sense, a fluid is defined as any substance that can deform under an applied shear stress. This includes both liquids and gases, which exhibit fluid-like behavior.
What is the difference between conductive and convective heat transfer mechanisms?
Conductive heat transfer occurs through direct contact between materials, while convective heat transfer involves the movement of fluids to transfer heat. Conductive transfer is more efficient in solids, while convective transfer is more effective in liquids and gases.
What is difference between compression waves and shear waves?
Compression waves, also known as longitudinal waves, involve particles oscillating parallel to the direction of wave propagation. Shear waves, on the other hand, involve particles moving perpendicular to the direction of wave propagation. Compression waves can travel through both solids and fluids, while shear waves can only propagate through solids.
What are the two forms in which sound can travel?
Sound can travel through solids, liquids, and gases. In solids, sound travels through vibrations of particles, while in fluids (liquids and gases), sound travels through compressions and rarefactions of the medium.
