The mass of the system consisting of the ice cube and the plastic cup will remain 5 grams even after the ice completely melts. This is because of the Conservation of Mass principle, which states that mass is not lost during a phase change.
The principle operating in this scenario is called the Conservation of Mass. In this specific context, this principle means that the mass of an object or a system of objects will remain the same regardless of the changes it may undergo, as long as no mass enters or leaves the system. In the case of an ice cube melting, although the physical state (phase) of the water changes from solid (ice) to liquid (water), its mass does not change.
So when an ice cube that weighs 5 grams (along with the cup) melts, it turns into an equivalent mass of liquid water. That means even after the ice has completely melted into water, the mass of the water and the plastic cup will still be 5 grams.
This is because during the phase change, only the state of the matter is altered (from solid to liquid), not its mass. The water molecules in the ice rearrange themselves and move apart during melting allowing the ice to become liquid water, but the number of molecules and thus the mass stays the same.

Answer:
Scientist use the scientific method to test theories.
Explanation:
Scientists use a range of skills, primarily the scientific method, and tools, such as various lab equipment and technology, to conduct their research.
Scientists use a variety of skills and tools to conduct their research and investigations. The primary skill they possess is the scientific method, a systematic way of understanding the world around us, which involves observation, question formulation, hypothesis testing, data collection, data analysis and conclusion drawing.
As for tools, scientists use a range of laboratory equipment like microscopes and pipettes for biological research, telescopes for astronomical studies, spectrophotometers for chemical analysis, computers for data analysis, and more. Technology is greatly used in science as it aids in thorough and precise investigations.

you two may go into a relationship. Taking a bullet would be if your strongly in love with someone. engaged marriage kind of love in my opinion. This could also just be a crush and maybe one day your not interested in this guy anymore and/or didnt end up going in a relationship. Good luck if things work with this guy or not :)
