1 HEAT TRANSFER. BROWNIAN MOTION. DIFFUSION ЖЫЛУЛЫҚ ҚОЗҒАЛЫС, БРОУНДЫҚ ҚОЗҒАЛЫС, ДИФФУЗИЯ

2 Мақсат молекула-кинетикалық теорияның негізгі қағидаларын дәлелдейтін мысалдар келтіру және тәжірибені сипаттау You will describe experimental proofs and show examples of Molecular Kinetic Theory (MKT)

3 Azamat uses air freshener, Ruslan stands 10 meters away from Azamat and measures time when he starts to feel smell. a) What may the measured time be? b) The speed of freshener molecules is about 600 m/s. Why does the smell reach Ruslan slowly?

4 Brownian Motion Random movement of Pollen Grains in Water

5 Brownian Motion The random (кездейсок) movement of microscopic particles in a liquid or gas, caused by collisions (соқтығыс) with molecules of the surrounding medium.

6 Diffusion - particle net movement from a region of High concentration to a Low concentration

7 The Kinetic Theory of Matter The kinetic theory is a way to describe the motion of particles. It states that particles in all forms of matter (solid, liquid and gas) are in constant motion, (either vibrating, sliding or flying around.)

8 Molecular Kinetic Theory (MKT) There are three basic assumptions in a molecular-kinetic theory. All matter consist of (құралады) of small particles. The particles are in constant (тұрақты) irregular motion. The particles interact (әсерлесу) with each other.
