Why is styrofoam cup a good insulator?
Styrofoam cup is a good insulator because it is coated with foam
What is conduction?
There are two kinds of conduction: thermal conduction and electrical conduction.In thermal conduction, thermal energy (heat) transfers through a substance from a hotter region toward a cooler region. For example, when you dip a metal spoon into a cup of tea, the heat from the hot tea will conduct along the spoon so that the handle becomes warm, even though the handle is not in direct contact with the hot tea.In electrical conduction, free electrons pass through a substance, thus enabling an electric current.Some materials are better conductors than others. Most metals are good thermal conductors, and certain metals (copper, aluminum) are very good electrical conductors. When a material is an exceptionally poor conductor, we call it an insulator. Styrofoam is a good thermal insulator, and glass is a good electrical insulator.
What type of cup can keep a hot drink the warmest?
In my science class last year, we did an experiment on this. The cup that kept the heat the best out of the ones that we tried was a Styrofoam cup.
Which cup keeps hot water the hottest polystyrene or metal?
Polystyrene (especially the expanded "Styrofoam (R)" type) is a good insulator. Metals are good conductors of heat.The insulating cup will maintain a greater heat differential than the conductor so if there is a liquid in the cup that is at a greater temperature than the surroundings, the metal cup will loose more heat than the polystyrene cup.
What makes a paper cup a good insulator?
A paper cup is not the best insulator. A better insulated cup is the foam cup. However, it is better insulated than other materials such as a metal canteen, due the the heat capacities of the materials. Putting two paper cups to together acts as a decent insulator due to the air between the two cups. This is due the to air being a poor conductor of heat.
Why does a styrofoam cup keep hot chocolate warmer then a glass?
If the Stainless Steel cup has no insulation the Styrofoam cup will keep it warm longer.
Why is styrofoam cup a good insulator?
Styrofoam cup is a good insulator because it is coated with foam
Is a metal cup a better insulator or a plastic cup a better insulator?
Putting the cup in the freezer keeps ice from melting. Those cups will slow down the melting rate, but if you've got ice at room temperature it's gonna melt eventually. Having said that, ice will melt slowest in a styrofoam cup.
Why does styrofoam cup keep drinks hot longer?
Styrofoam is an excellent insulator.
Which type of cup has better insulation?
A Styrofoam cup has the best type of insulation. These are better cups because they have the lowest thermal conductivity.
Is a foam coffee cup a conductor or a insulator?
Styrofoam, along with most other expanded plastics, is a very poor insulator of heat and electricity, thereby making a foam coffee cup a very good insulator.
Is tea cosy a thermal insulator?
Yes, a tea cozy could be considered a type of thermal insulator. This is because it keeps the heat from escaping the cup holding the tea.OH HEEL NO
Is a china cup a thermal insulator?
with so many other things out there to use as an insulator it would seem a very bad choice, but yes it would bea good insultor, electricity will not flow through it.
What is a styrofoam cup?
a cup made out of styrofoam...........................................................................................................................................................................
What type of cup will keep a drink warmer?
a type of cup that will keep a drink warmer is a thermos, you can get them in many different sizes (cup sizes). they can be found in any household goods stores even woolworths.
Does a styrofoam cup equal 3 liters?
if its a small Styrofoam cup definitely not
