The kinetic-molecular theory explains the properties of the gases in terms of energy, size and motion of their particles.
The assumptions that the kinetic-moletuclar theory makes about the characteristics of gas particles are:
1. Gases are constituted by a large amount of particles (atoms or molecules) symilar to solid spherical sphers, in constant and random motion.
2. Gas particles move in straight line until collide with another particle or the walls of the vessel.
3. Gas particles are so small compared to the distances that separate them, that the volume of the gas is considered empty space: the volume of the particles is neglected.
4. Beside the already mentioned collisions with the walls of the vessels or between the particles, there is no interaction (attractive or repulsive forces) acting on the gas particles.
5. The collisions between gas particles or with the walls of the vessel are elastic: there is not loss of energy.
6. The average kinetic energy of the particles in a gas depends only on the absolute temperature of the gas: at a given temperatue every gas have the same average kinetic energy.
That collection of assumptions are used to explain such things as: the relation of pressure withthe number of particles, the relation of pressure and temperature, the relation of pressure and volume, the relation of volume and temperature, Avogadro's hypothesis (relation of volume and number of particles), Dalton's Law of partial pressures, and both effusion and difusion.
Answer:
High amplitude is equivalent to loud sounds.
Explanation:
Larger the amplitude, the higher the energy. In sound, amplitude refers to the magnitude of compression and expansion experienced by the medium the sound wave is travelling through. This amplitude is perceived by our ears as loudness.
Hello!
The answer is C. Hibernate during the cold winter months.
Why?
Alpine marmots are known for having a long hibernation duration which starts in October (winther) and ends in April (summer) (about 7 months). During this long period, they are able to reduce their bear beats from 200 per minute to just 30 or 38 beats, and their breaths from 60 breaths/minute to 1-3 breaths/minute, guaranteeing an extreme energy saving process.
Have a nice day!
