Which styrofoam cooler provides more cooling

In general, solids make better heat conductors than liquids or gases, and gases are the poorest of the three states of matter. Styrofoam is structured as microscopic air bubbles contained by relatively stiff walls.

And even though the material is a good thermal insulator, some heat does pass through it, albeit slowly. Chicago native John Papiewski has a physics degree and has been writing since He has contributed to "Foresight Update," a nanotechnology newsletter from the Foresight Institute.

Styrofoam is the trademarked name for polystyrene foam. This petroleum-based plastic is lightweight and serves as an effective insulator.

As such, it does a great job of keeping heat out of things like coolers. Because it is relatively firm, it also helps provide a degree of protection for items while in transit from one place to another. Some materials — especially metals — conduct heat well while others — like Styrofoam — conduct it poorly. Both types are useful in certain circumstances, but when it comes to protecting items in a package from the heat of the outside environment, you need a material that is a poor conductor.

This helps keep the cool air inside the package while keeping the hot air out. How Styrofoam Insulates Styrofoam is primarily made of air. Show that the mass of ice that melts is 50 g. To melt ice to 50g of water,. If the coefficient of sliding friction for steel on ice is 0. Look at the position of Location 1, Location 2, and Location 3 in this picture.

Simple diagram of a lake represented by a wavy circle. The circle is labeled 'Lake,' and there are three points outside of the lake: 'Location 1' is. Dry ice is solid carbon dioxide. When dry ice is added to warm water, heat from the water causes the dry ice to sublime more quickly. What is the maximum mass that can hang without sinking from a
