Recycling one aluminum can save enough energy to charge the average smartphone for 14 hours?

Recycling one aluminum can save enough energy to charge a TV for 3 hours?

Recycling one aluminum can give an indicudualy roughly the energy to recycle 19 more aluminum cans?

Can someone please show the calculations for these energy equivalents? Thank you!

Expert Solution

The energy estimations are relative. So, here are the informations which can provide a basis for the above energy estimation.

Aluminum. Recycling of aluminum cans saves 95% of the energy required to make the same amount of aluminum from its original source. One ton of recycled aluminum saves 14,000 kilowatt hours (Kwh) of energy, 40 barrels of oil, 238 million Btu's of energy, and 10 cubic yards of landfill space.

These estimations can be figured from similar data obtained for metals, alloys or materials which can either be crystalline or amorphous as follows:

Steel. One ton of recycled steel saves 642 Kwh of energy, 1.8 barrels of oil, 10.9 million Btu's of energy, and 4 cubic yards of landfill space.

Glass. One ton of recycled glass saves 42 Kwh of energy, 0.12 barrels of oil (5 gallons), 714,000 Btu's of energy, 7.5 pounds of air pollutants from being released, and 2 cubic yards of landfill space. Over 30% of the raw material used in glass production now comes from recycled glass.

If it has enough kinetic energy, a molecule at the surface of the Earth can escape the Earth’s gravitation. The acceleration of gravity is 9.8 m/s2, and the Boltzmanns’ constant is 1.38066 × 10−23 J/K. minimum kinetic energy needed to escape in terms of the mass of the molecule m, the free-fall acceleration at the surface g, and the radius of the Earth R. 1. Kmin = 1 m g R 3 2. Kmin = 1mgR 2 3. Kmin...

One photon or particle of light has enough energy to cause biological damage if the particular form of electromagnetic radiation is ultraviolet UV light, an X-ray or a gamma ray. There have been some claims that the use of cell phones causes brain damage. (We’re talking about physical damage from irradiation not psychological dependence or a car crash while dialling.) Search reference materials or use the Internet to find out where cell phones fit on the energy scale. Use the...
