Methanol is sometimes used as an antifreeze. It can be added to water in car windscreen wash bottles to prevent them from freezing in cold conditions . The percentage of anti freeze that helps to prevent an object from freezing till a specific point in °C are as follows:

10% = -5

20% = -12

30% = -21

•Tania puts a mixture containing 10% antifreeze into the wash bottle of her car. During the night, the temperature dropped to -14°C . The wash bottle burst, explain why?

i think the answer is terrae but not 100 percent sure. ▓▬▬ §

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.
