Initial Activity- What mass of solute will dissolve in 100g of water at the following temperatures?
pantera1 [17]

The mass of solute will dissolve in 100g of water at the following temperatures will be  153 gms, 40 gms, 70gms simultaneously.

<h3>How dissolution of solute is affected by temperature ?</h3>

On increasing temperature the amount of solute for dissolution decreases.

It is independent of the nature of solute.

Hence,

  • KNO₃ at 70degree = 153 gms
  • NaCl at 100 degree = 40 gms
  • NH₄Cl at 90 degree = 70gms

Two magnetic field lines never intersect each other.why?
PIT_PIT [208]
If the magnetic lines of force intersected each other, then that would violate the laws of physics.

If the lines intersected, then at the point of
intersections there would be two directions of magnetic field force, and this cannot defy the laws of physics, so therefore it does not happen.

A good example of this would be if you had a
compass and you tried to use it to view the field direction. If you had two lines of force
intersecting, then the compass would have to
point in both directions, and that can't happen both theoretically and through observation.

An event like that would generate a monopole, which is an impossible, theoretical magnetic event.
