Is heat of fusion an extensive or intensive property? Why?

1 answer:

5 0

Answer:

Temperature is an intensive property, while heat is an extensive property. An intensive property means that the amount of substance present will not change the specific trait. Calorimetry, heat of fusion and heat of vaporization calculations.

The graphics in the attachment is part of the question, which was incomplete.

Answer: Fr = 102N and angle of approximately 11°.

Explanation: From the attachment, it is observed that from the three forces acting on M, two are perpendicular. So to find them, we have to show their x- and y- axis components. From the graph:

Fx = 70+40-10 = 100

Fy = 40-20 = 20

Now, as the forces form a triangle, the totalforce is:

Fr = $\sqrt{Fx^{2} +Fy^{2} }$
