Question
Explain characteristics and structure of silicon using a neat labelled diagram.

Answer

$1.$ Silicon $(Si)$ has atomic number $14$ and its electronic configuration is $1s^2 2s^2 2p^6 3s^2 3p^2.$
$2.$ Its valence is $4.$
$3.$ Each atom of $Si$ forms four covalent bonds with its neighbouring atoms. One $Si$ atom is surrounded by four $Si$ atoms at the comers of a regular tetrahedron as shown in the figure.

One of the effects of a force is to change the momentum. Define the quantity related to this and explain it for a variable
force. Usually when do we define it instead of using the force?
To understand the process of change of state:
Take some cubes of ice in a beaker. Note the temperature of ice (0 °C). Start heating it slowly on a constant heat source. Note the temperature after every minute. Continuously stir the mixture of water and ice. Observe the change in temperature. Continue heating even after the whole of ice gets converted into water. Observe the change in temperature as before till vapours start coming out. Plot the graph of temperature (along Y-axis) versus time (along X-axis). Obtain a graph of temperature versus time
