The conversations need to solve this problem:
1 cal = 4.184 joules
1 Kcal= 1000 calories
1 kj= 1000 joules
or a more direct approach---->> 1 Kcal = 4.184 Kjoules
8.4 kcal (1000 calories/ 1 Kcal) x (4.184 joules/ 1 cal) x (1 Kj/ 1000 joules)= 35.1 Kj
or 8.4 kcal (4.184 Kj/ 1 kcal)= 35.1 Kj (same answer)
Answer: Option (c) is the correct answer.
Explanation:
In liquids, molecules are held by slightly less strong intermolecular forces of attraction as compared to solids.
Hence, molecules of a liquid are able to slide past each other as they have more kinetic energy than the molecules of a solid.
As a result, liquids are able to occupy the shape of container in which they are placed. Also, liquids have fixed volume but no fixed shape.
Thus, we can conclude that liquids have a variable shape and a fixed volume.
