Which insulator did the best job and which was the worst? Use key words, insulator, conductor, and thermal energy
Paper cup: 19.4 C
Foil cup: 18.0 C
Bubble wrap cup: 14.3 C
1 answer
The bubble wrap cup did the best job as an insulator, as it kept the thermal energy inside the cup the most effectively with a temperature of 14.3 C. The worst insulator was the foil cup, as it allowed the thermal energy to escape more easily with a temperature of 18.0 C.
