Conduction
Convection
Radiation
Explanation:
The main types of heat transfer are heat transfer by conduction, convection and by radiation.
These forms of heat transfer has different modes of application.
- Conduction is a form of heat transfer in solids. It requires a material medium to dissipate. Here, heat flows from a hot end to a cold end.
- Convection is a form of heat transfer in fluids i.e liquids and gases. In convection, heat is transferred due to density differences between heated fluids.
- Radiation does not involve material medium. It uses the electromagnetic waves to dissipate heat.

It is a reaction between an element and a compound that results in a different element and compound
<span>2AlBr</span>₃<span>+ 3Cl</span>₂<span>--> 2AlCl</span>₃<span>+3Br</span>₂<span> </span>
Then as the electrons in the atoms fall back down, they emit electromagnetic radiation (light). The amount of light emitted at different wavelengths, called the emission spectrum, is shown for a discharge tube filled with hydrogen gas in Figure 12.6 below.
The answer is (2) increases. The definition of excited state is that the electrons have higher energy than ground state. For comprehension, the excited state is ready for reaction so it has higher energy.
