Mechanics is the field of science focused on the motion of material bodies. Mechanics involves forces, energy, motion, deformation, and material properties. (True/False?) Both fluid and gases are called Fluid. Is fluid a substance whose molecules move freely past each other, that is, it flow under the action of shear stress. (True/False?) What is the definition of \'Solid\'? What is the definition of \'liquid\'? What is the definition of \'gas\'? State Continuum Assumption. Why using Continuum Assumption. An ideal gas, 1 atm and 20 degrees Celsius, one mole occupies 24.7 liters (+/-5%)? State two applications when the Continuum Assumption is invalid? Draw and briefly explain the fluctuation of density in Figure 1.4 (b) 10^th edition. If your text book is Not 10^th edition or different; okay, mention the edition, name of the text book and the page #. (For full credit: All the solutions must be written below this paragraph.

Solution

1) True. Mechanics is a branch of science which deals with bodies are in rest or motion. Mechanics also deals with forces,energy,material properties.

2) True. Both liquids and gases called fluids. Fluid is a substance which is dependent of shear stress.

3) A solid is a sample of matter that retains its shape and density when not confined. The adjective solid describes the state, or condition, of matter having this property

4) A liquid is a nearly incompressible fluid that conforms to the shape of its container but retains a (nearly) constant volume independent of pressure. As such, it is one of the four fundamental states of matter (the others being solid, gas, and plasma), and is the only state with a definite volume but no fixed shape.

5) Gas is one of the four fundamental states of matter (the others being solid, liquid, and plasma). A pure gas may be made up of individual atoms (e.g. a noble gas like neon), elemental molecules made from one type of atom (e.g. oxygen), or compound molecules made from a variety of atoms (e.g. carbon dioxide.

6) Continuum (measurement), anything that goes through a gradual transition from one condition, to a different condition, without any abrupt changes.

8) this statement is true

form relation PV = nRT

substitute all values we get volume as 24.45 which is approximately equal to 24.7
