Answer:
Water has a higher boiling point because the hydrogen bonds that form water molecules are stronger than the Van der Waals interactions among methane molecules, therefor more energy must be provided in order to break the hydrogen bonds and allow the water molecules to escape the liquid state.

Answer:
3.900 km/min
7.677 × 10⁵ ft/h
Explanation:
Step 1: Given data
Speed of the object (s): 6500. cm/s
Step 2: Convert "s" to km/min
We will use the following conversion factors.
6500. cm/s × (1 km/10⁵ cm) × (60 s/1 min) = 3.900 km/min
Step 3: Convert "s" to ft/h
We will use the following conversion factors.
3.900 km/min × (3280.84 ft/1 km) × (60 min/1 h) = 7.677 × 10⁵ ft/h
I belive this is known as coordinate covalent bond.
hope this helps!
