Answer:
Atom then element
Explanation:
Scientists once thought the most fundamental building block of matter was a particle called the atom. Now we know that the atom is made of many smaller pieces, known as subatomic particles. Every atom contains a central core called the nucleus, made of particles called protons and neutrons.
An element is a pure substance and is made of only one type of atom; it cannot be broken down into a simpler substance.

When a metal such as copper is heated,it expands. Can anyone tell me what happens to the metal particles as the solid metal expands?
Answers
Answer:
The metal molecules inside start to vibrate faster, causing the solid to change to liquid if exposed to the intense temperature over a long period of time.
Explanation:
As my answer states, but for an explanation, lets say you are boiling an ice cube, it will start to turn into liquid water, that is because it has been exposed to that heat for a long period of time. The same will happen for the metal, if its exposed for long enough, it will turn into a liquid, then can be turned into a gas because the molecules are vibrating so quickly that they start to easily move apart.
Hope this helps, let me know if any more clarification is needed.

If a person consumes 50% of their daily kilocalories from carbohydrates and 30% from protein, what percentage of their daily kilocalories will come from fat?
Answers
The percentage of daily kilocalories of the person that come from fat is 20%.
The diet of a person is composed mainly of carbohydrates (C), proteins (P) and fat (F), that is, the sum of the 3 sources amount to 100% of the consumed kilocalories. Given that 50% of the daily kilocalories of this person come from carbohydrates and 30% come from protein, the percentage that comes from fats is:
[tex]C + P + F = 100\%\\F = 100\% - C - P\\F = 100\% - 50\% - 30\% = 20\%[/tex]
The percentage of daily kilocalories of the person that come from fat is 20%.

The volume (V) of an enclosed mass of gas is 350kPa. The pressure of the endlosed gas is now decreased to 125kPa, at constant temperature. What will the new volume of the gas be, in terms of V (2)
Answers
Answer: V1/V2 = 0.357,
V2 = (V1/0.357) or 28.0*V2
Explanation: Use the combined gas law: P1V1/T1 = P2V2/T2 We want to find V1/2 (or V2/V1). Rearrange:
V1/V2 = (P2/P1)(T1/T2)
The units all cancel. Temerature is constant, so (T1/T2) = 1.
V1/V2 = (125/350)*(1)
V1/V2 = 0.357
