Dark surfaces are the best.
any surfaces really! just not rough stuff like sandpaper!
For hot metal surfaces, the best paint to use is a high-temperature resistant paint, typically formulated with silicone or epoxy resins. These paints can withstand extreme temperatures, often exceeding 1000°F (538°C), without degrading or losing adhesion. It's essential to choose a paint specifically designed for metal surfaces to ensure durability and prevent rust. Brands like Rust-Oleum and Valspar offer high-heat options suitable for applications like grills, engines, and exhaust systems.
To reduce friction, which is a resistance between two surfaces in contact. The points of contact between moving parts in a machine create heat (which is actually a desired effect in a flintstone, in which one strikes a flintstone with another rock to create heat as a means of starting a fire) and cause damage in their grinding against one another. Oil reduces the friction, which reduces the heat generated and the damage from the moving part surfaces grinding against one another; this reduction in friction is called lubrication.
The best way to make homemade clay firm is to heat it up. You can heat the clay up in an oven.
Hot gluing is used lots in arts and crafts. Also, minor repairing of laminated surfaces around the home. Be careful when gluing surfaces that can melt with high heat, like Styrofoam - best to use regular glue for that. Just a added note: I have received gifts (a bird house) that was put together with hot glue, it fell apart. there are better glues out there. Depending on the use and the material you are gluing, consider handling, indoor, outdoor, etc. Good-Luck!
Black is a color that is good at radiating heat as it absorbs most of the energy that it receives and then emits it as heat. This is why black surfaces often feel warmer to the touch compared to lighter colored surfaces.
Smooth and shiny surfaces such as metal or glass are good at radiating heat quickly to the surroundings due to their high thermal conductivity. Additionally, surfaces with dark and matte finishes tend to radiate heat more efficiently compared to light and shiny surfaces.
Silver is about the best for conduction, with copper not far behind. For radiation, a black body is best, and will radiate more heat the hotter it is. The sun for instance acts as a black body with temperature about 6000 deg C.
Dark, rough surfaces are typically better absorbers of heat compared to light, smooth surfaces. This is because dark surfaces absorb more light and convert it into heat, while rough surfaces have a greater surface area for heat absorption.
black dull surfaces but im looking for why these surfaces are the worst?
Dark surfaces are the best absorbers of heat because they absorb a wider range of wavelengths of light, converting them into heat energy. Light surfaces, on the other hand, reflect more light and thus absorb less heat.
smooth, dark colored
Land surfaces heat up and cool down faster than water surfaces.
NO! Ideal materials for radiating heat are black. If a body is radiating lots of heat then its electromagnetic(EM) spectrum should peak below the visible range(Infrared region),making the material look dark.
Shiny metallic surfaces, polished surfaces, and light-colored surfaces are poor radiators and absorbers of heat. These surfaces reflect more heat energy than they absorb, which results in lower heat gain.
The cancer was caused by excessive nuclear radiation exposure. Some members of the military may have been exposed to high levels of radiation.
Heat promoting mechanism include exothermic reactions and the radiating of heat through conductance. Exothermic reactions include the combustion of carbon based fuels which release heat. The radiating of heat can come from electronic space heater that release warmth through their conducting metal filaments.
