Teaching notes. mass x specific thermal capacity x temperature / time = current (amps) x p.d. The ratio temperature rise / time can be obtained from the slope of a graph of temperature plotted against time. 2 The aluminium blocks can be lagged by enclosing them in foamed polystyrene.
An abyssal plain is an underwater plain on the deep ocean floor, usually found at depths between 3,000 metres (9,800 ft) and 6,000 metres (20,000 ft). Lying generally between the foot of a continental rise and a mid-ocean ridge, abyssal plains cover more than 50% of the Earthâs surface. They are among the flattest, smoothest and least explored regions on Earth.
There is no light in the Abyssal Plain because the dept in meters is 3000-6000 and light from the surface cannot reach that far down. SALT The amount of salt changes throughout this ecosystem. The salt level is between 34 and 35 parts per thousand. Which is 3.4%- 3.5% salt!
