What would you expect to observe when you add flour to a glass of water

It will kind of make like a type of tough or soft dough

Explanation: If you add too much water it might be a dough that bearly tays together or is very soft, but if you add too little it will be hard to mold. The reason it forms a sort of consistency like this is because When water is added to flour and mixed, these proteins absorb water, otherwise known as hydrating. Gliadin and Glutenin then combine to form the protein called GLUTEN. ... When flour is mixed with water, the gluten swells to form a continuous network of fine strands.

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.
