Short course annotation in Lithuanian

Kursas yra skirtas mechanikos pagrindams ir medžiagų termodinaminėms savybėms studijuoti. Dujų, skysčių ir kietųjų kūnų savybės susiejamos su jų mikroskopine sandara. Nuosekliai nagrinėjami mechanikos dėsniai, kurie reikalingi kūnus sudarančių dalelių judėjimui ir sąveikai aprašyti, mikroskopinės ir makroskopinės kūnų būsenos kaita susiejama su termodinamikos dėsniais ir entropija, nagrinėjami cikliniai procesai bei šių procesų energetinis efektyvumas, aptariamos skysčių ir kristalinių kūnų struktūrinės ir šiluminės savybės.

Short course annotation in English

The course is designed to study basics of mechanics and thermal properties of substances. Properties of gases, liquids and solids are related to the microscopic characteristics of particles from which materials are formed. The course includes topics as motion laws of solids, conservation laws, macroscopic and microscopic state of the system, the laws of thermodynamics, the return and non-return processes, Carnot process and efficiency, entropy, surface tension, introduction to the physics of solid state.

Prerequisites for entering the course

General mathematics

Course aim

The aim of the course is to explain physical and thermal properties of gases, liquids and solids and relate these properties to microscopic and macroscopic structure of matter.

Content (topics)

 1. Physical measurement: quantities, units and errors.
 2. Kinematics, the cause motion, forces.
 3. The laws of conservation
 4. Oscillation, properties of sound.
 5. Models of bodies. Statistical and thermodynamic methods
 6. Properties of gases.
 7. Laws of thermodynamics.
 8. Heat, work and internal energy of the bodies.
 9. Cyclic processes, heat engines in nature and technology
 10. Heat capacity, the phase changes
 11. Physical and thermal properties of liquids
 12. Physical and thermal properties of solids

Practical work (contents):

1. Measurement on force table. 2. Motion laws on air bench. 3. Investigation of string oscillation. 4. Measurement of expansion of metals. 5. Measurement of coefficient of thermal conduction. 6. Measurement of adiabatic constant for air. 7. Measurement of air viscosity. 8. Measurement of water viscosity. 9. Investigation of surface tension.

Distribution of workload for students (contact and independent work hours)

Lectures – 45 hours, laboratory work in computer class – 30 hours,  individual work – 85 hours.

Structure of cumulative score and value of its constituent parts

Final assessment sums the assessments of written final examination (50%), written mid-term examination (25%) and assessment of laboratory works (25%).
