results.

Important experiments

Lesson -1

Q1. Image formation with concave mirror

Lesson - 2 : 3 experiments 

Q1. The reaction between quicklime and water. 

Q2: precipitate formation reaction"

Q3: the reaction between zinc and hydrochloric acid. 

Lesson -4 

Q1: the image formation with the convex mirror. 

Lesson - 5

Q1: prism experiment. 

Lesson -9

Q1: ohm's law verification 

Q2: the factors that affect the resistance of a conductor.

Factors are 👇

the length of the conductor, the cross-sectional area of the conductor, the material it is made of (its resistivity), and the temperature of the conductor. 

Lesson -10

Q1: Oersted's experiment,

Ans: the materials required are: a battery (9V), insulated copper wire, a magnetic compass, a switch, a sheet of paper (optional), and two small wooden sticks (optional) to help hold the wire in place. 

Observations

The compass needle deflects when placed near a current-carrying wire 

The needle deflects in the opposite direction when the current's direction is reversed 

The amount of deflection increases as the current's magnitude increases 

The deflection decreases as the compass needle is moved away from the wire 

The magnetic field lines encircle the wire 

The magnetic field lines lie in a plane perpendicular to the wire 

Q2: solenoid experiment 

👉 Note: In this experiments mostly asked material required or observations 

Lesson -11

Q1: Factors that Affect the Rusting of material

Lesson - 12

Q1: The esterification experiment
