Answer:
A and B
Explanation:
This is because there was emission of gamma (Y) radiations in both the reactions.
A weak bond between two molecules resulting from an electrostatic attraction between a proton in one molecule and an electronegative atom in another
Answer:At the molecular level, the pressure of a gas depends on the number of collisions its molecules have with the walls of the container. If the pressure on the piston is doubled, the volume of the gas decreases by one-half. The gas molecules, now confined in a smaller volume, collide with the walls of the container twice as often and their pressure once again equals that of the piston.
