Questions

The first option is incorrect because it is devoid of blood cell, also red blood cells so doesn’t contains haemoglobin.

The second option is incorrect because plasma is colorless.

The third option is also incorrect because plasma contains the clotting factors.

The four bonds of carbon tetrachloride (CCl4) are polar, but the molecule is nonpolar because the bond polarity is cancelled by the symmetric tetrahedral shape. Hence, making the net dipole as zero and molecule as non-polar.

When other atoms substitute for some of the Cl atoms, the symmetry is broken and the molecule becomes polar.

We want the temperature when F=C.

We know that, F = C x 95 + 32

So substituting C For F, we have C = -40o

Therefore,  C = -40. 

Thus when C = -40, we have C = F
