The water in the tank that you are transferring the angelfish to should be the same temperature and PH of the old water.
If you are adding them to your tank from a fish store, then you should acclimate the fish first by floating the bags in your tank, and every so often add a bit of your tank water to the water in the bag to avoid temperature or PH shock.
yes, if there is not enough water the heat will be affected because not as much heat can be held.
By transferring heat steam/ hydronics /scorched air
A heat conductor is something which is could at transferring heat. Think of a metal spoon in a pan of boiling water. The spoon feels hot because the metal is good at transferring the heat to your hand. On the other hand, an insulator is something which is bad at transferring heat. They can be used either to keep heat in, or to keep it out. For instance, because air is a good insulator, hot water tanks often are covered in foam, which traps air, which helps to keep the heat in.
Water is a good conductor of heat because it is a liquid thus convection currents can flow as well as transferring heat by conduction through the water molecules.
They both have to do with the transfer of heat. Heating an object is transferring heat into the system. Freezing an object is transferring heat out of the system.
its a good conductor of heat
The role convection currents play as you heat a pot of water is transferring heat by movements of a liqiud or a gas because when when convection occurs it occurs in a circular pattern.
Radiation
Heat energy
Yes because you are transferring heat
Conduction
The earth receives heat from the sun as radiation
