Environmental Studies

By Clare Smith

Many debatable environmental concerns revolve round advanced clinical arguments, which are greater understood with a seize of the most important clinical options. Environmental Physics presents an advent to the actual rules that underlie environmental concerns and exhibits how they give a contribution to the interdisciplinary box of environmental technology as a whole.

Example text

The Universe is gradually increasing its entropy, as it spreads out and cools down. This is described by the Second Law of Thermodynamics, which states: In any closed system, entropy can never decrease. A hot bath will cool down, warming a cold bathroom in the process, until air and bathwater are both lukewarm. Within this closed system—the bathroom—energy is conserved, but entropy has increased. The heat cannot be collected from the air and used to heat the bath again, without external energy input.

If such an object experiences vibrations at the appropriate frequency, it will absorb energy readily. 18 A simple electrical circuit. atmosphere by gases—the frequency of the electromagnetic radiation is the same as a resonant frequency in the gas molecules. Resonance in larger objects can cause them to vibrate, which may result in structural damage in buildings or bridges. During a pop concert in Finsbury Park, north London, the band Madness sang their well known crowdpleaser ‘One Step Beyond’, accompanied by thousands of their audience stamping and dancing in tune with the music.

Above the Curie point, the thermal energy of the atoms is too great to retain a permanent magnetic field, as the vibrations break down the field. If a piece of hot, ferromagnetic material such as iron or iron-bearing rock is allowed to cool in the presence of a magnetic field, as it passes through the Curie point it will pick up the magnetic field and become a permanent magnet. This process occurs when rocks form, and when any iron object is smelted. When a rock is in the form of hot magma, it cannot become permanently magnetised, but as it cools through the Curie point, it will pick up the Earth’s magnetic field, producing remanent magnetisation in the rock.
