A student melts 50.0 grams of ice using 16650 j of energy. what is the heat of fusion of ice?

1 answer:

5 0

The heat of fusion of the ice is the amount of energy that is required in order to melt one gram of ice. In this item, in order to solve for the heat of fusion, we simply have to divide the given energy by the mass.
heat of fusion = 16650 J / 50 g = 333 J/g
Thus, the heat of fusion of the ice is 333 J/g.

Answer:

Here are the labels:

6. Zygomatic bone

7. Vomer

8. Mandible

9. Maxilla

18. Sternum

19. Costal cartilage

20. True ribs

21. False ribs

22. Floating ribs

Explanation:

The skull comprises the 8 cranial bones that house and protect the brain and 14 facial bones that protect the sensitive organs such as eyes, nose and mouth.
Out of the 14 facial bones, the mandible, maxilla, zygomatic and vomer along with the frontal bone are the primary bones of the skull.
The rib cage comprises of 12 pairs of ribs connected to the sternum, the main bone that anchors the rib cage, through the costal cartilage.
The ribs numbered 1 to 7 are called true ribs because costal cartilage connects these bones directly to the sternum.
The ribs 8 to 12 are classified as false ribs because they are not directly connected to the sternum.
The last two ribs 11 and 12 are called floating ribs because they do not connect to the sternum at all.
