A tool might be made of an alloy because the alloy _____.
A. occurs naturally
B. resists rust
C. can bend easily
D. is softer
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.

Pepper has the same state of matter after it is mixed with water.
What is the state of matter?State of matter of any substance tells about the physical appearance or the space occupied by the atoms of that substance.
From the given option; carbon dioxide, salt and sugar are soluble in water and changes their state of matter to liquid. But pepper is hydrophobic in nature that means it is not soluble in water, so present in the original state after mixing with water.
Hence, option (c) is correct i.e. pepper has the same state.
