All things are made of matter. Matter has three forms. They aresolid,liquid, andgas. A solid is matter with its own shape. A rock and a book are solids. Even if we move a solid, it keeps its shape. A liquid is matter thatflows. Water and oil are liquids. A liquid does not hav...
The apparatus includes a swirl vanes device for reducing the velocity of exhaust fumes fed into an enclosed container with the accompanying direction and volume changes enhancing the separation of the exhaust into gas, liquid, and solid components. Solids and liquids collect in the container and ...
