When sandpaper is rubbed against rusty metal, friction is generated between the sandpaper and the metal surface. This friction causes heat to be produced due to the resistance between the two surfaces. The heat is a result of the kinetic energy being converted into thermal energy.
Yes, example: he blasted the rusty metal with sand.
A steel object that is rusty will appear orange or reddish-brown in color due to the presence of iron oxide on its surface. The surface may also have a rough, flaky texture, with visible corrosion spots and damage to the metal. Rust can form when steel is exposed to moisture and oxygen over time.
Maybe. The question is ill-defined as written. If I take a metal object of known mass, and let it rust in such a way that none of the rust crumbles and falls off the object, the rusty object will indeed have a slightly greater mass than the original object did.
A rusty nail may weigh more than a new one due to the oxidation process. Rust is formed when iron reacts with oxygen, adding mass to the nail. The rust layer can make the nail heavier than when it was in its original form.
Rust is a heterogeneous mixture. It is formed when iron reacts with oxygen and water in the presence of moisture, leading to the formation of iron oxide compounds on the surface of the metal. This process results in a mixture of different compounds with varying chemical compositions.
To fix a rusty bike, start by removing the rust using a wire brush or sandpaper. Then, apply a rust converter or primer to prevent further rusting. Finally, repaint the affected areas to protect the metal from future corrosion.
The metal is getting rusty!
With a fingernail file or sandpaper or both. If it's too rusty, throw it out.
A RUSTY METAL FRAME WILL HAVE NO EFFECT AT ALL ON your garden produce
This metal is iron.

To achieve a rusty appearance on metal surfaces, you can use a combination of vinegar, hydrogen peroxide, and salt to create a rusting solution. Apply this solution to the metal surface and allow it to sit for a period of time to develop the desired rusty look.
by how rusty it is :) x
The reaction with oxygen
Rusting is one of the possible form of corrosion of metals
This could be rusty.
