The Earth behaves as if there is a huge bar magnet at its centre. The shape of the field around the Earth is very similar to the field around a bar magnet

If a molecule can hydrogen bond does it guarantee that it will have a higher boiling point than a molecule that cannot?
sleet_krkn [62]
A molecule that can h-bond will not always necessarily and does not have guarantee to have a higher boiling point than one than cannot have h-bond.
we can take an example of Pentan-2-one that cannot h-bond but instead of this it  has a high boiling point that is 102.3 °C, while propan-1-ol can h-bond but it has a boiling point of 97.2°C, that is lower than the boiling point of Pentan-2-one.

Replacing standard incandescent light bulbs with energy-efficient compact fluorescent lightbulbs can save a lot of energy. Calcu
EleoNora [17]

Answer:

a) 1512000 Joules

b) 5040 seconds = 84 minutes = 1.4 hours

Explanation:

Power saved y replacing bulbs = 60-18 = 42 W = 42 J/s

Time the bulb is used for = 10 hours

Energy saved during this time

42×10×60×60 = 1512000 Joules

Saved energy by replacing standard incandescent lightbulbs with energy-efficient compact fluorescent lightbulbs in 10 hours is 1512000 Joules

b) Power the plasma TV uses = 300 W = J/s

\frac{1512000}{300}=5040\ s3001512000=5040 s

Time a plasma TV can be used for with the saved energy is 5040 seconds = 84 minutes = 1.4 hours.
