Which particles have more kinetic energy-those in a substance with a high temperature or those in a substance with a low temperature?

Answer 1

The quality of an answer depends in part on the quality of the question. I am guessing that we are comparing for total thermal energy at fixed given temperature, a given number of particles with a larger number of particles. It makes a difference whether the actual particle makeup stays the same. In other words, we are comparing say some number of particles of Teflon with a greater number of particles of Teflon, and NOT some number of particles of Teflon with a greater number of particles of say iron, or salt; or size A particles compared to size B particles. In that case, yes, the more particles of the same kind, the more energy.

Thermal energy is proportional to the mass times the absolute temperature times the specific heat, and specific heat depends on the molecular type and arrangement.

Answer 2

In hot water particles move faster therefore speeding up the transfer of energy. ChaCha again soon!

Answer 3

The intermolecular forces are weakened.

Answer 4

Not only are the intermolecular forces weakend, but the particles have greater kinetic energy, i.e. they move faster.

Answer 5

the higher it's temperature!:)

Answer 6

Their molecules vibrate more.
