Please make in English also madam
IN the assumption 4..what kind of force act during collisions?
bhai neet 2019 me help kre
how to calculate final volume if 1/4 gas is escaped from the container??
ye Hindi me hai vidio kyo pagal bana rahe ho sir😡
a gas is filled in a container of volume v at 121°c to what temperature should be heated that 1/4 th of gas is escaped???? plz help me wid this
