In your lab group, you are in investigating the properties of matter. Your teacher gives you several unknown substances to identify. Select ALL of the PHYSICAL properties that might help you differentiate between the unknowns. A: Color
B: Texture
C: Flammability
D: Boiling point
E: Reaction with acid

etween the unknowns.

give me abc and i will get it for u.

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.
