A Styrofoam cup keeps drinks warm because the Styrofoam offers excellent insulation, which keeps the liquid warm inside. While a Styrofoam cup can keep drinks warm, a thermos container captures heat to keep drinks hotter for longer.Know More
According 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 cup.Learn more about Solutions & Mixtures
Styrofoam is a plastic made from petroleum, and it is also called a styrene monomer. Styrofoam is the brand name for polystyrene foam.Full Answer >
Only paints that are specifically labeled as being compatible with Styrofoam should be used with the material. Failure to do so can damage the Styrofoam and cause craters and holes in a craft project.Full Answer >
A solution is a mixture featuring solutes that have been dissolved, while a suspension is a mixture of liquids also containing solid particles that may not completely dissolve inside the liquid. Materials that dissolve in liquids are considered soluble. When no more solute dissolves in a particular solvent while temperature remains the same, the solution is considered to be saturated.Full Answer >
In chemistry, a filtrate is a liquid that has passed through the filtration process. In this process, liquid is strained. Bigger particles get stuck in the strainer, while smaller particles and liquid pass through, becoming filtrate.Full Answer >
