Test Preparation

Matter is made up of very small particles.  These particles cannot be seen with our naked eyes. Matter exists in three states - solid,liquid and gaseous states.

Matter and it's Characteristics (in Kannada)

Matter changes from solid state to liquid state and then to gaseous state upon heating. Upon cooling gas becomes a liquid and liquid changes to solid . Some solids directly change to gas without forming a liquid.  This phenomenon is called sublimation.

Inter-conversion of Matter (in Kannada)

Elements and compounds are called pure substances while mixtures are called impure substances. 

Elements can again be classified into metals,  non-metals and metalloids.

Pure and Impure Substances (in Kannada)

A mixture contains two or more elements or elements and compounds. The components of the mixture are not in any definite proportion. 

We have two types of mixtures- homogeneous mixtures and Heterogeneous mixtures.

Mixtures - Homogeneous and Heterogeneous Mixtures (in Kannada)

There are different methods to separate components of a mixture like evaporation, filtration, distillation, sublimation etc. Depending on the components different methods are used.

Methods of Separating Components of a Mixture (in Kannada)

General science includes physics,chemistry and biology.

General Science: KPSC

Living organisms are classified into five kingdoms based on some similarities and differences.

Classification of Living Organisms

There are two types of cell divisions- Mitosis and Meiosis which take place in the living organisms. In this course, the educator discusses Cell Division for KPSC.
