Max is helping his parents move to a new house. He picks up one box and is able to carry it into the house. He tries to pick up a second box with an identical volume, but he is unable to lift it. What is most likely the difference between the two boxes?
Answers
Answer:
The Weight
Explanation:
Even know it has the same volume does not mean it has the same mass and weighs the same with the items inside the box. Most likely, that the Items inside the box are heavier then the first box Max moved.
Max is helping his parents move to a new house. He picks up one box and is able to carry it into the house. He tries to pick up a second box with an identical volume, but he is unable to lift it. The difference between the two boxes is weight.
What is, an identical volume ?Similar items have the identical volume. In other words, two items have the same volume if all of their measures completely match. An object's volume remains unchanged when it is rotated or reflected.
According to Avogadro's law, all gases with an identical volume and the same temperature and pressure have an equal number of molecules. If the temperature and pressure are constant, the volume and amount (in moles) of an ideal gas for a given mass are directly proportional.
The relationship between mass and volume can be easily determined using density; for example, the mass of a body is equal to its volume multiplied by the density (M = Vd), whereas the volume is equal to the mass divided by the density (V = M/d).
Thus, He tries to pick up a second box with an identical volume, but he is unable to lift it. The difference between the two boxes is weight.

A tool might be made of an alloy because the alloy _____.
A. occurs naturally
B. resists rust
C. can bend easily
D. is softer
Answers
Your answer is:
B. Resists rust.
A tool might be made of an alloy because the alloy resists rust.
Why?
Iron is a great building material but steel (an alloy made by adding small amounts of non-metallic carbon to iron) is stronger, harder, and rustproof. Aluminum is a very light metal but it's also very soft in its pure form.
Alloy steels have a wide range of special properties, such as hardness, toughness, corrosion resistance, magnetizability, and ductility. Nonferrous alloys, mainly copper–nickel, bronze, and aluminum alloys, are much used in the coinage.

An ecosystem is the interaction between the abiotic and biotic factors in an area.
What is an ecosystem?Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.
Energy enters the ecosystem through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil. There are different ecosystems present in the world.
