Anything that displaces a fluid feels an upward pressure equal to the weight of that volume of fluid. That is called buoyancy, or floating. It's hard to imagine a piece of steel floating, but the upward force of the displaced air reduces the measured weight. A warm object expands, so it displaces more air and is lighter.
Most materials, and all metals, absorb air and that increases their mass. A warm material might expel some of the air, removing some mass.
Air around the object rises when heated and the turbulence of moving air can cause random readings of the weight. Precision scales have doors to exclude air movements, and some scales use a vacuum chamber.
Antoin Lavoisier, the French guy who invented chemistry, wrote a book explaining how to reproduce his experiments. He devoted an entire section to describing his very precise scales and other instruments. One of them was in the basement of a building: the entire basement. The house was empty, existing only to cover the basement, and the basement was insulated with bark chips to prevent outside heat from causing inside air currents. There was a tiny door to load the scale, and a tiny window to observe the measurement. You can download his book "Elements Of Chemistry" Kindle edition.
Yes, matter can be weighed using a scale or balance. The weight of an object is a measure of the gravitational force acting on it. By measuring this force, we can determine the mass of the object.
i believe, and i may be wrong, bet the force required to move the object in the water will be less than the force required to move the object through the air. the best bet for you to see this is to try it for yourself.
Taring a balance ensures that the weight of the container holding the object is not included in the final measurement, giving an accurate reading of the object's weight alone. This helps in obtaining precise and reliable measurements of the object being weighed.
A balance is a first-class lever, where the fulcrum is located between the effort (force applied) and the load (object being weighed).
Common errors in measuring accuracy of an object include human error, instrumental error, environmental factors, and systematic errors from calibration issues. Additionally, inconsistent measurement techniques and insufficient sample size can also lead to inaccuracies in measuring accuracy.
A hot object produce a lowering of air density around the balance and this produce an error in balance reading.The sample must have the same temperature as the balance. Balances are frequently designed to work correct at 20 oC.

The weight depends on the force of gravity at the point where the object is weighed.

Yes, a solid can be weighed on a scale. The weight of a solid is the force exerted by gravity on the object, which can be measured in units like grams or kilograms.

Depends where you weigh it. This is really pedantic but weight is a force acting on an object due to gravity, not an inherent characteristic of the object. The Earth has a mass of 6.0x1024 kg. If you weighed it on the Earth (?) it would weigh 6.0x1025 Newtons but on the moon just 7.21023 N.
An object that weighs 100 pounds on Pluto would weigh 262 pounds on Earth, assuming the same mass of the object. This is because weight is proportional to the gravitational force acting on an object, and the gravitational force is stronger on Earth than on Pluto.
A pound is a measure of mass, not weight so an object cannot weigh 115 pounds. Assuming that you meant the object weighed 115 poundals, the answer is 1.62 kilograms.
An object that weighed 100 pounds, would weigh 236 pounds on Jupiter.
