b.exists as a liquid
c.exists as a crystalline solid
d.exists as an amorphous solid
Answer:
c.exists as a crystalline solid
Explanation:
Amongst all the three phases, it is solid phase which is the most compact because the atoms within the solids are bound with a very strong force of attraction. But, solids can exist as either crystalline solid or amorphous solid. Between these two type of solids, it is crystalline solids which are very well packed and the inter atomic distance between their two atoms is the least. It is due to the reason that the atoms within a crystalline solid are arranged in proper order in the form of stacks. But, in amorphous solids the atoms are not arranged properly i.e. their arrangement is random which leads to the increased inter atomic distance. Second comes liquid phase, in liquids the inter atomic forces are intermediate between solids and gases. Atoms in a gas are bound with the weakest force of attraction known as van der Waals that is why the distance between the atoms of a gas is the highest.
B. 651.605 kPa.
C. 277.280 kPa.
D. 448.955 kPa.
By definition we have to:
Where,
Pabs: absolute pressure
Patm: atmospheric pressure
Pg: gage pressure
The atmospheric pressure is constant and its value is:
Then, by clearing gage pressure we have:
Substituting values we have:
Answer:
If the absolute pressure of a gas is 550.280 kPa, its gage pressure is:
D. 448.955 kPa
b. If the cd rotates 4 times per second, what is the linear speed of a point on the outer edge of the cd? Give
