The pressure that  will  be   exerted if  four sample  of gas are placed in a single  3.5 container  is calculated as below

if  each gas occupies 675  mmhg

what about  4 gases in the sample
by cross  multiplication

= 675 mm hg x 4/1 = 2.7  x10^3mmhg (answer D)

How does a multicellular organism develop?
crimeas [40]

Answer:

The cells differentiate.

Explanation:

Organism can be simply classified on the basis of the cellularity of the organism. Two main types of organism are unicellular organisms and the multi cellular organisms.

Multicellular organism contain different types of cells.  The different cells differentiate to perform a particular function. The division of labor property is well shown by the multi cellular organism. The cells of the multi cellular organism must show differentiation process.

Thus, the correct answer is option (d).

Calculate the speed of light in water. The speed of light in air is 3.00 x 108 m/s.
xz_007 [3.2K]

Answer:

225,563,910 m/s

Explanation:

speed of light in water = speed of light in the air/refractive index

speed of light in water = 3.00 x 10^8 m/s/1.33

speed of light in water = 225,563,910 m/s

At high pressures how does the volume of a real gas compare with the volume of an ideal gas under the same conditions and why
malfutka [58]
Answer: No, a<span>t high pressures, volume of a real gas does not  compare with the volume of an ideal gas under the same conditions.

Reason: 
For an ideal gas, there should not be any intermolecular forces of interaction. However, for real gases there are intermolecular forces of interaction like dipole-dipole and dipole-induced dipole. Further, at high pressures, molecules are close by. Hence, extend of these intermolecular forces is expected to be high. This results in decreases in volume of real gas. Thus, </span>volume of a real gas does not  compare with the volume of an ideal gas under the same conditions.
