The pressure inside a hydrogen-filled container was 2.10 atmatm at 21 ∘C∘C. What would the pressure be if the container was heated to 93 ∘C∘C ? Express your answer with the appropriate units.

2.61atm

Explanation:

The following were obtained from the question given:

P1 = 2.1atm

T1 = 21°C = 21 + 273 =294K

T2 = 93°C = 93 + 273 = 366K

P2 =?

Using P1/T1 = P2/T2, we can calculate for the new pressure as follows:

P1/T1 = P2/T2

2.1 / 294 = P2 / 366

Cross multiply to express in linear form

294 x P2 = 2.1 x 366

Divide both side by 294

P2 = (2.1 x 366) / 294

P2 = 2.61atm

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.
