Why are styrofoam cups good for testing calorimetry of bombs?
Because syrofoam is a good insulator so it keeps most of the heat in the calorimeter. It also has a low specific heat
Why are foam cups used for both hot and cold drinks?
Foam - styrofoam is an excellent insulator. With a hot drink - you want it to remain hot - so you do NOT want heat to move out of the drink to the cooler outside. The styrofoam vastly reduces this heat flow. With a cold drink, the reverse is true. You want it to remain cold so you do not want heat to move from your hand or the outside atmosphere into the drink. The styrofoam vastly reduces this heat flow.
How do I keep an object cold that is near a heat source long term doesn't have to be more then a few degrees?
The best available insulation is a vacuum flask; failing that, Styrofoam is quite effective as well. Put something in a sealed Styrofoam container with some ice, and it will stay cold for a long time, even if it is near a heat source (within reason; too much heat will destroy the Styrofoam, of course).
Is liquid styrene flammable?
It is the worst insulator because all the small holes in it makes all the heat that it is holding in come out.Plus it is bad to the enviroment.ANS 2 High density styrofoam is an excellent insulator. -Some people just don't understand that all styrofoam is NOT the same, it comes in many grades.
How does styrofoam insulate?
millions of tiny gnomes hold hands blocking the transfer of heat or lack there of
What is the specific heat of a styrofoam cup?
1.3 kJ/(kg·K)
Is styrofoam a better insulator of heat than plastic?
Styrofoam is a better insulator of heat than plastic. The plastic allows the heat in and out and the cold in and out. The Styrofoam helps keep the heat in.
Why are styrofoam cups good for testing calorimetry of bombs?
Because syrofoam is a good insulator so it keeps most of the heat in the calorimeter. It also has a low specific heat
How well does styrofoam conduct heat?
Yes, styrofoam is full of air cells and air is a good thermal insulator. Styrofoam has poor solvent resistance, and poor hot performance.
What contains styrofoam that heat cannot easily transfer?
Styrofoam contain a great quantity of air - air is a heat insulator.
How do you melt a styrofoam cup?
Heat will do it
Why is styrofoam an insulator?
Styrofoam has pockets of air. These pockets make it harder for heat to travel through.
What keeps heat in an aluminum can the longest?
styrofoam
Objects that absorbs and radiate heat?
Styrofoam
Which has a higher heat capacity copper or styrofoam?
Copper
Why does styrofoam get better heat retention?
Styrofoam is a good material for retaining heat. This is because its formation is that of tightly packed air-filled, tiny bubbles of plastic and is fairly thick, which prevents heat from escaping.
How much does Styrofoam cost?
200,000 joules of heat are needed to produce a single styrofoam cup. In order to simulate the waste of a styrofoam cup, its ceramic counterpart would have to be used 70 times or washed over a thousand times to offset the loss of heat in one styrofoam cup.
