1. ‘Transfer of water’
I turn on a tap in my bathroom and put a glass under it. The glass
fills with water. The reason is that the tank stores water high up
in the roof. Water flows from the tank to the glass, which is lower.
So the glass fills up.
2. ‘Forms of water’
I turn on a tap in my bathroom and put a glass under it. The glass
fills with water. The reason is that the cold water tank in the roof
contains cubic water (the shape of the tank). This is changed into
running water in the pipes, and then into cylindrical water in the glass.
This can be summarised:
cubic water -> running water -> cylindrical water
3. ‘Forms of energy’
I connect up a battery to a small coil of wire, which I put in a beaker
of oil. The oil gets hot. The reason is that the battery contains
chemical energy. This is changed into electrical energy in the wires,
and then into heat energy in the oil. This can be summarised:
chemical energy -> electrical energy -> heat energy
4. ‘Transfer of energy’
I connect up a battery to a small coil of wire, which I put in a beaker
of oil. The oil gets hot. The reason is that the battery is
a store of concentrated energy. Energy is transferred from the battery
to the oil, where it is less concentrated. This makes it get hot.
