Acids typically taste sour, which is characteristic of many acidic substances like lemon juice and vinegar.

Radiation can refer to heat produced by the Sun (solar radiation), heat emitted by electronic devices, and heat produced by heaters. All these processes involve the transfer of energy through radiation.

The process involved in water heating is convection, which is the transfer of heat through the movement of fluids (liquids or gases).

In water, heated water rises while cooler water sinks, creating a convection current that distributes heat throughout the liquid.

Both water and air are considered poor conductors of heat compared to metals. They can transfer heat, but not as efficiently as good conductors like copper or aluminum.

Materials that do not allow heat to pass through them are called insulators. They resist heat flow and are used to prevent heat transfer in various applications.

Materials that allow heat to pass through them are called conductors.

They facilitate the transfer of thermal energy efficiently, with metals like copper and aluminum being common examples.
