Does the temperature affect a rubber band?

Answer 1

Yes, and here's why. Rubber derives its elasticity from entropy. The molecules are long and stringy, like a bowl of pasta, and form an interpenetrating network. The lowest energy state is the most random. When rubber is stretched, the molecules slide past one another and become oriented. This is a thermally activated process called reptation. If there is enough thermal energy, the molecules can explore enough of the configuration space to find a path for displacement. If there is not enough thermal energy, the molecules get stuck together and displacement requires breaking covalent bonds.

Answer 2

confident it does, yet in a slightly unpredicted way. in assessment to maximum supplies, which expand whilst heated and settlement whilst cooled; rubber expands (relaxes) whilst cooled and contracts (loses elasticity) whilst heated. this is the inspiration of a properly-liked technology lab test: a wheel is created making use of rubber bands as against the steel spokes. A warmth lamp is shone on the rubber bands on one edge of the hub. using fact the settlement, the wheel will become unbalanced and starts off to tutor. The rubber bands that circulate away the concentration of the warmth lamp cool and return to ther unique length, and the subsequent set are heated. This cycle repeats, and the wheel turns under the potential of the warmth lamp.

Answer 3

Yes, you can stretch it further in warm weather and it will sna sooner in cold weather

Answer 4

Yes. In heat, it becomes more pliable, and in cold, it becomes more brittle.

Answer 5

yes , chuck one in a furnace and see what happens

Answer 6

heat it stretches, cold it shrinks and gets easily broken

Answer 7

yes!
