CHEMISTRY EXPECTED QUESTIONS WILL RELEASES SOON
Rain drops acquire spherical shape due to - Surface tension
It is more difficult to walk on ice than on a concrete road because - there is very little friction between the ice and feet pressing it
Skating on ice is possible because - the pressure on the ice due to skate melts the ice by lowering its melting point forming a thin film of water
Formation of shadows can be explained by - rectilinear propagation of light
Energy posses by a body in motion is called - Kinetic Energy
If lift is going up with acceleration, the apparent weight of a body is - more than the true weight
Sudden fall in barometer is indication of - Storm
What is Hooke’s Law - Stress is directly proportional to strain.
Lognitudinal waves and Transverse waves are types of - Mechanical waves
What are audible sound waves - Having frequency between 20 Hz to 20000 Hz
Stars appears to move from east to west because - the earth rotates from west to east
Metals are good conductors of electricity because - they contain free electrons
Rectifiers are used to convert - Alternating current to Direct current
Magnetism at the centre of a bar magnet is - zero
Elecronegativity is the measure of - Non-metallic character
