Please help and show work If 22.0 L of a gas at 155 kPa changes to a volume of 10.0 L then what is the new pressure if temperature is constant- {Boyle’s law}

If 20.0 L of oxygen at – 25°C is heated to 100°C and pressure remains constant, find the new volume- {Charles’s law}

Iknow #2 is d. i just need to know why

This drawing shows a human body system. what is the primary function of this body system?

Plz mark brainliest 30 points1) find the momentum of a 12 kg snowball that is rolling with a velocity of 9 m/s.2) an 8 ball with a mass of .5 kg is sitting at rest. it is hit by the cue ball (1 kg) traveling at 2.5 m/s. if the cue ball is at rest after the collision, how fast is the 8 ball traveling after the collision? 3) two football players are running toward each other. if the offensive player is 75 kg and is running 8 m/s, how fast must the 60 kg defensive player run in order for the two players to hit and stop?
