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.

Gay-Lussac’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-Lussac’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. Charle’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

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.

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.
