An inflated basketball with a volume of 2.5 liters is left outside. When the ball is found outside, the volume of has decreased to 1.8 liters and the pressure of the ball is 1.2 atm. What was the original pressure of the basketball? reposting this bc i didnt get a serious answer last time :(

no but i do not usually comment or use my voice that much when it comes to social media

it can be observed without changing the identity of the object.

it depends on what substance you're talking about as well as many other factors. in quantum mechanics, the observation of particles affects the observers ability to measure certain properties. for example: you can know the velocity of a particle, but you can't know it's position; or you can know it's position, but not it's velocity. it's like trying to find out where a grain of sand is by throwing other grains of sand at it. once you find out where it is, it's been moved. it's also like trying to find an answer to the question of whether or not a tree falling in a forest makes a sound if nobody is there to hear it. paradoxically, the only way to find out is to be there and hear it.

c. orbital shape i hope this is correct
