#### What is a Bimetallic strip & what are its uses?

If equal lengths of two different metals, such as copper and iron, are riveted together so that they cannot move separately, they form a bimetallic strip (Figure 1). figure 1: ...

#### Conduction, Convection, & Radiation – Energy transfer during heating & cooling

There are three different processes through which energy can be transferred during heating and cooling: conduction, convection, and radiation. Conduction is the transfer of heat through a substance as a ...

#### Internal energy of a substance – Definition and Different forms

To describe the total energy of the molecules in a substance, we need to take into account both the kinetic energies and the potential energies. This is called the internal ...
