Answer:

1) Water vapor condenses to form water droplets: a physical process.

2) It is proportional to its weight.

3) Gas

4) 115.2 °C since melting point is an intensive property

Explanation:

1) rusting of metals involves oxidation which is a chemical process

hydrogen and oxygen undergoes chemical reaction to give water

If a candy is dropped in water and releases gas then there must be some reaction going on,

thus out of the four changes, condensation of water is a physical process.

So correct answer is

Water vapor condenses to form water droplets: a physical process.

2) Mass is independent of location, It will be the same on earth or on moon,Its weight which changes with locations.

Thus the correct answer is mass is proportional to weight.

3) gas particles are neutral and they bounce off on another as they collide. the gas particles are in random motion due to high thermal energy and low intermolecular forces of attractions.

4) The intensive properties does not depend upon the mass or amount of a substance. Melting point is an intensive property and will be the same for any amount of a given substance.

Poor precision in scientific measurement may arise from
Arturiano [62]
<span>Based on the experience of the responder, to correctly calculate measurements in real-world. Firstly is to avoid errors as much as possible. Errors are what makes your measurement invalid and unreliable. There are two types of error which is called the systematic error and the random error. Each error has different sources. Words that were mentioned –invalid and unreliable are very important key aspects to determine that your measure is truly accurate and consistent. Some would recommend using the mean method, doing three trials in measuring and getting their mean, in response to this problem.</span>

What is Force? I'll Mark BRAINLIEST ​
Luda [366]

Answer:

A push or pull is referred to as a force. Forces can cause objects to move, slow, stop, or change the direction in which they travel. The force of gravity, for example, pulls all objects toward the Earth's center. Every time two things interact, a force is exerted on each of them. When this happens, the two items no longer feel the force after the interaction ends.
