Which type of cup keeps hot water hottest polystyrene plastic paper or metal?

Charlie is testing whether thing swim sink or float he put a plastic-foam board in the water predict whether the board will sink or float.explain your reasoning put a plastic-foam?
Water has a density of about 1.0, knowing this you can tell if an object will sink or float by calculating the objects density.
What is the difference between closed cell foam insulation and open cell foam insulation?
Closed-cell foam insulation differs from open cell foam insulation in the fact that closed-cell foam insulation has tiny foams cells that are closed and packed together. They are filled with gas that helps the foam rise. Open cell foam does not have this characteristic.
Which gas helps the foam that fire fighters use?
In a Compressed Air Foam System (CAFS), air or another gas is compressed and introduced into the foam solution. Larger systems use a dedicated air compressor and compresses regular air from the atmosphere.Smaller systems can use any inert compressed gas such as Carbon Dioxide (CO2), Compressed Nitrogen (N2) or smaller tanks of compressed regular air.The simplest, most efficient and least expensive way of producing foam is with a portable foam eductor. These foam systems use regular hand lines and an eductuor 100 feet from the end of the nozzle. The eductor siphons foam solution from a tank or drum using the "Venturi" principal. When the foam solution reaches a standard fog nozzle, water pressure and the broken stream produced by the nozzle introduce air into the foam solution.There are other forms of nozzles that introduce water using the "Venturi" effect that are not user adjustable like a fog nozzle.The quick easy answer is regular air is used most commonly in fire fighting foam however CO2 and N2 can be used depending on the design of the system used.In a Compressed Air Foam System (CAFS), air or another gas is compressed and introduced into the foam solution.

Is a foam pillow a conductor or an insulator?
This depends on the type of foam. There have been made foam that actually conduct electricity. This is a choice made in the manufacturing of the foam. Most foam in mattresses and the like does not conduct electricity. Moisture however can change the mattresses conductivity drastically.
Does plastic keeps liquid hotter than a foam container or a glass container?
Plastic generally does not keep liquid hotter than a foam container or glass container. Foam containers have better insulating properties, making them more effective at retaining heat. Glass containers also have higher thermal conductivity, which can help keep liquids hotter for longer periods compared to plastic.
What is hotter to hold paper or foam cups?
a foam cup i guess but what kind of question is that
If boiling water was poured into a china cup and a foam cup which cup would feel hotter explain?
china cup
What is ceramic foam filter?
Ceramic foam filter is the refractory ceramic material. It is used for filtration of molten metal,gas,water and so on.
Which type of cup keeps hot water hottest polystyrene plastic paper or metal?

What is the difference between aspirated foam and non aspirated foam?
Aspirated foam is created by mixing foam concentrate with air using a foam inductor or aspirating nozzle, resulting in lower density and longer reach. Non-aspirated foam is created by directly injecting foam concentrate into water, resulting in higher density and shorter reach. Aspirated foam is typically used for longer distance applications, while non-aspirated foam is used for shorter distances with higher extinguishing capability.
Is firefighter foam better than water?
yes, because many modern fires contain chemicals and other elements that burn hotter, and are often not affected by water. foam works better because it is specifically designed to put out fires that are either not affected by water, or become more intense when water is added, much like grease fires that arise when cooking.
What are the obstacles on wipeout made of?
foam and metal and plastic
Record how high the foam floats in water?
Record how high the foam floats in water.
What are the top three tips for creating inviting floral designs?
Use your floral foam effectively be creative with it. Mix your colours create interesting shades. Always soak your floral foam in water to help you arrangement last longer.
Is dirt a good insulator?
is foam dirt an metal a good insulator
What two things have the same mass but different volume?
A metal ball and a foam ball can have the same mass but different volumes. The metal ball will be denser and therefore have a smaller volume compared to the foam ball.
