Explain the processes of melting and boiling, and identify different methods for boiling water and what happens when you put a kettle in a microwave.

The solid wax around the flame is melting and changing into liquid wax. This happens because the heat from the candle flame transfers energy to the solid wax.

This is happening because the heat from the candle flame raises the temperature of the solid wax. When the wax reaches its melting point, it absorbs enough energy to change its state from a solid to a liquid.

Here are three different ways to boil water:

• Using an electric kettle.
• Heating it in a pot on a stove (gas or electric hob).
• Using an immersion heater directly in a container of water.

If you tried to put a typical metal kettle into a microwave, it would cause sparks and could damage the microwave oven or even start a fire because metal reflects microwaves. If you put a stovetop kettle on a stove, it would heat up and boil the water inside, which is its intended use. If it were an electric kettle (which is usually plastic or has electronic components), putting it on a stove would melt or damage it.
