Styrophoam because it has a lot of particles squished together, while the ceramic cup has only fiber and very few particles. And the more particles in any substance equals a warmer being.
styrofoam, but warning fammable and unsafe for the environment!
thermos cup
Hot cocoa will stay hotter for longer in a glass compared to a styrofoam cup because glass has better insulating properties than styrofoam. Styrofoam is a poor insulator, allowing heat to escape more quickly.
Styrofoam cups and caps. It keeps the heat in.
Styrofoam because it has a thick layer and is a good insulator.Paper and plastic are could alternatives but Styrofoam would work better, therefore glass would be the worst one to use because it would only keep it warm for a couple of minutes.
Regular stainless steel irons can be hotter to the touch, while ceramic will be cooler.
Flat irons get hotter, so they do more damage.
If the containers are the same apart from the colour, no. But if the red container is more insulated than the blue one, yes If the blue is more insulated than the red, no.
A roof made of zinc is hotter because, unlike ceramic, it reflects the sunlight and radiation off of the surface. On the other hand, ceramic absorbs the light, and the heat is trapped inside, so no heat escapes. Therefore, it is not as hot as the zinc would be.
Actually coffee does not stay hotter in a ceramic cup vs a Styrofoam cup, but would stay hotter in a ceramic cup vs a paper cup.A good insulator for a water based liquid will reduce conduction and convection. Styrofoam works well keeping coffee warm because it has a small mass and a large volume. The small mass helps eliminate conduction. The large volume is because the sintering process traps tiny pockets of air that help eliminate convection. With those two together you get hot coffee longer.
white or silver metallic. a vacuum insulated thermos mug will do even better, the the outside color doesn't matter.
It is designed to hang in the air, insulated from the hot metal walls of the oven, which could be (and usually are) hotter than the air or the food being cooked.
