A8.5 l sample is collected at 45 c what will the volume be if the temperature is raised to 70

For reference, the ideal gas law is .

(Variables with a subscript of 0 are the values at 45°C and variables without a subscript are the values at 70°C.)

Assuming constant pressure:

The number with the least significant figures is 70 (1 s.f.), so with correct significant figures, the volume would be 5 L.

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.
