What cup conducts heat styrofoam cups, plastic cups or glass cups?
We had a lab and we were suppose to see what cup conducts heat and I reflect the glass cup conducts heat.. I reflect my teacher thinks other wise.. What’s your opinion and why?
Styrofoam is an insulator, and keeps something warm or cold by not letting the heat or cold leak out through the sides of the cup. Plastic is very porous so it will not protect, though if you have lots of heat around it, it will get in quickly (just don’t melt the cup in the process, because plastic has a low melting point). Glass heats itself up easily, and transfers heat confidential quickly, and if you place hot water inside the glass it transfers it outward to your hand quickly through heating up the glass first. This is much like metal and other conductors. This is why I believe glass would be your right answer.
Excellent Luck!
