They argue about the nature of the phenomenon of free falling bodies. In order to proceed in the experiment, the researchers needed to: acquire the given bodies' mass, diameter and volume which are composed of the big marble, small marble and the metallic ball, compute for their acceleration and from then using the data that have been collected and computed form a logical and equitable conclusion. Provided that the researchers has finished and thoroughly did the experiment they we're able to prove that Aristotle's theory-that the mass and volume of a given body falls faster compared to lighter objects, is precise. However, Galileo's theory-that objects regardless of their mass and shapes moves in a constant acceleration towards the ground is precise as well provided that you will disregard the air resistance.

In a piston-cylinder device the working substance is initially at 100 kPaa and 0.025 m3 then expands reversibly until the volume becomes 0.105 m3. The process is in accordance with pV1.25. determine the work done in the process.
2. A cylinder tank, 75 cm in diameter and 150 cm high, is filled with a fluid whose density is 40 lb/ft3. What is the total mass of the fluid?
3. 200 kJ of work is delivered to a closed system. If the initial volume is 0.6 m3 and the pressure of the system changes as p = 8 – 4V, where p is in bar and V is in m3, determine the final volume and pressure of the system.
4. A hiker is carrying a barometer that measures 101.3 kPa at the base of the mountain. The barometer reads 85 kPa at the top of the mountain. The average air density is 1.21 kg/m3. Determine the height of the mountain.

A substance is said to be pure substance if its chemical compositions do not change even in solid, liquid, or gaseous phase. Example of which is water that has two atoms of hydrogen and one atom of oxygen as it is in solid, liquid or gaseous state. State of pure substance or system refers to its condition as quantified or identified through the thermodynamic properties of the substance. Phase is a quantity of substance that is homogeneous throughout. Relevant Reversible Work Modes refers only to the important work modes for the system in question and irreversible work modes are not considered. Reversible work mode refers to the amount of energy added in a forward process that can be removed by the reversed process.

It provides emphasis on the analytical and graphical study of displacement, velocity and acceleration. This also includes the study of the elements of mechanisms such as gears, train, rolling bodies, belt and pulleys, cams and followers.
