The First one! A.. Water freezes at 0 and boils mostly at 100 or more
Answer:
C)It would require more energy to change solid water into liquid water because there are more molecules in this larger piece of ice.
Answer:

Explanation:
You calculate the energy required to break all the bonds in the reactants.
Then you subtract the energy needed to break all the bonds in the products.
N₂ + O₂ ⟶ 2NO
N≡N + O=O ⟶ 2O-N=O
Bonds: 2N≡N 1O=O 2N-O + 2N=O
D/kJ·mol⁻¹: 941 495 201 607

Neither the speed nor the distance of a falling object is linearly related to time.
