Final answer:

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.

Explanation:

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:

A pill is usually absorbed into the blood through the stomach walls after it is swallowed – these can become active in a few minutes but usually take an hour or two to reach the highest concentration in the blood. IV drugs are injected directly into the blood work much faster – sometimes in seconds or minutes.

Answer:

300 J.

Explanation:

• The first law of thermodynamics is the law that demonstrates the conservation of energy.

• It states that the total energy of an isolated system can not be created or destroyed, but it may be transformed into another form.

• The energy released to the room is 300 J.

• So, according to the law of conversation of energy; the amount of heat removed from food inside of the refrigerator is 300 J.
