Complete this paragraph, which describes an ice cube changing from a solid to a liquid to a gas.
AB
Water can exist in three states of matter. Imagine examining the changes of state from solid to liquid to gas by adding
thermal energy to ice. What would change or not change?
As water changes state, the mass of the sample does not change the size of the water molecules
does not change However, the spacing of the water molecules does change during a change in state. The
evidence that supports this conclusion is that the volume of the sample changes.

the food using pesticides in the future will harm you by giving you diseases like cancer or something since they have things that we should not eat in it like chemicals or pesticides. that is why organic food is more expensive because they take the time to make it right and healthy for you to eat.

explanation:

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.
