In general, foam is a better insulator than metal, and so foam would be expected to keep water hotter longer under most normal circumstances.

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.

Glass or plastic what keeps water colder?

Glass is a better insulator than plastic, meaning it is better at keeping the temperature of its contents stable. Glass has a lower thermal conductivity compared to plastic, which helps to prevent heat transfer between the water inside and the surrounding environment. This makes glass more effective at keeping water colder for longer periods of time compared to plastic.

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 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.


When does foam from algaecide go away?

Foam from algaecide typically dissipates within a few hours to a couple of days, depending on factors such as water temperature, agitation, and the specific algaecide used. Warmer temperatures and increased water movement can help speed up the breakdown and dispersal of the foam. Additionally, the foam may persist longer in stagnant or cooler water conditions. Regular maintenance and filtration can also help reduce foam more quickly.

How can I effectively insulate pipes to prevent heat loss and save energy?

To effectively insulate pipes and prevent heat loss, you can use pipe insulation materials such as foam or fiberglass sleeves. These materials wrap around the pipes to create a barrier that reduces heat transfer. By insulating your pipes, you can save energy by keeping hot water hotter for longer periods and reducing the need for your water heater to work as hard.
