How wouldo I do research on which cup would keep a hot drink warmer

marshall27 [118]

ccording to Michigan State University, heat is created when molecules in the liquid move in different directions and bang into one another. These fast moving particles hit the side of the container where they are located. Heat conduction causes the heat from the liquid to be transferred to the container. The container gets hotter while the liquid gets colder. The liquid also loses heat as the surface area is exposed to air. The air gets heated while the container and the cup cool down.

A thermos container keeps liquids hot because the tight lid prevents heat from escaping the container. The core of the thermos is also filled with insulation, which does not conduct heat as well, so the liquid inside the cup does not cool down as quickly. Most thermos containers also feature reflective exteriors that limit the heat lost to radiation. A Styrofoam cup is made up of 95 percent air. This air conducts heat, which draws the warmth from the liquid into the cu

Match each of the following descriptions to thecorrect element listed

Slav-nsk [51]

Answer: Please see explanation for answer

Explanation:Matching the descriptions to the correct element listed gives

Element Group Name Group No Metal/ Nonmetal/ Metalloid Description

Neon Noble gases 18 Non metal Colorless, tasteless, and odorless gas, unreactive, nonconductive.

Bromine Halogens 17 Non metal Not found as a free element (uncombined) in nature, reddish-brown liquid that vaporizes readily at room temperature to a red gas with a strong disagreeable odor.

Beryllium Alklaline earth metal 2 Metal Silvery-white, ductile, malleable, conductive solid with a high melting point for this type of element

Platinum Platimum group metals 10 Metal Silvery white, relatively soft, low density, conductive solid that is not found as a free element in nature but commonly found combined in alloys with copper or nickel

Potassium Alkali Metals 1 Metal Soft, easily cut with a knife to expose a silvery surface that rapidly oxidizes in air; never found uncombined in nature

Silicon Carbon family 1`4 Metalloid Metallic luster and grayish solid, very common in rocks and gemstones such as amethyst and opal, semiconductor

Sulfur Calcogens 16 Non metal Pale yellow, odorless, brittle solid at room temperature, nonconductor
