The plastic cups I can get have thin walls. This means the water without ice stays as water because any temperature changes to the water will not last very long. Insulated cups have thick walls so they will cool liquids cool and hot liquids hot
Both beakers will weigh the same amount when filled to the same level with water, regardless of whether one has a plastic ball floating in it. This is because the weight of the water displaced by the plastic ball in the second beaker is equal to the weight of the ball itself.
Yes, a plastic bowl can float on water because plastic is less dense than water. This means that it displaces enough water to stay afloat.
Some plastics are more dense than water, most are not.

You can but you don't need the water. If you blanch the peas and they freeze them on a cookie sheet you can then put them in a plastic freezer bag. This way they stay separated and you can use a portion of them without thawing the whole batch.
No. It gets hotter - that is not the same
Caterpillars do not drink water. How are they able to stay alive
After water has been boiled, its mass will stay the same.
It stays the same.
If the plastic can stand going up to 100 celsius without melting, the water will gradually heat up and the plastic bottle will remain at the water temperature. Eventually the water will start to boil at 100 celsius. If the bottle is closed it will explode under steam pressure. If the steam can escape, the bottle will stay at 100 celsius until the water has evaporated, then it will rapidly heat up and melt.
no
It stay the same
