The word oscillatory refers to something that moves back and forth repeatedly. The word periodic refers to something that repeats after a regular amount of time. While oscillatory motion will almost certainly be periodic, not all periodic motion will be oscillatory.
A. No. Because x = A, at extreme. and Force is given as    So
A process  is called polytropic process  And Specific heat For polytropic process is given by
Work done in the adiabatic process is given by
Gay-Lussacâ€™s law states that if the volume remains constant, then the pressure of a given mass of a gas is directly proportional to its absolute temperature. Gay-Lussacâ€™s law is obeyed in Isochoric process. We will learn this in this concept.
Charle's law states that, if the pressure remaining constant, the volume of the given mass of a gas is directly proportional to its absolute temperature. Charleâ€™s law is obeyed in Isobaric process. We will learn this in this concept.
According to it heat given to a system (Q) is equal to the sum of increase in its internal energy (U) and the work done (W) by the system against the surroundings. I.e \Delta Q = \Delta U + \Delta W
For a cyclic process the clockwise area will show positive work and anticlockwise area will show the negative work done
It is called the "zeroth" law because it came to light after the first and second laws of thermodynamics had already been established and named, but was considered more fundamental and thus was given a lower number , i.e zero.
Yes. The ratio of two extensive properties of the same object or system is an intensive property. For example, the ratio of an object's mass and volume is called density, And density is an intensive property. But both object's mass and volume are extensive properties.
Open system - an open cup of coffee, closed system-a cup of coffee with a lid on it
A. The heat capacity at constant pressure C_p is greater than the heat capacity at constant volume C_v , because when heat is added at constant pressure, the substance expands, so the heat added during constant pressure is used to do external work also.
Assumption taken is that the mass of each molecule and diameter of each molecule is constant. Then only condition of hyperbola is satisfied.
No, it is not true. Each molecule may have velocity greater, equal or less than R.M.S. velocity of the gas. You will study about it in this concept.
Q.Let us take a fixed amount of gas in a chamber. So, each molecule of this gas must have the velocity equal to r.m.s. velocity.Whether this is true or false? A. No, it is not true. Each molecule may have velocity greater, equal or less than R.M.S. velocity of the gas. You will study about it in this concept.
