Gas Ideal merupakan gas teoretis yang terdiri dari partikel-partikel titik yang bergerak secara acak dan tidak saling berinteraksi.
Termodinamika merupakan suatu ilmu yang menggambarkan usaha untuk mengubah kalor (perpindahan energi yang disebabkan perbedaan suhu) menjadi energi serta sifat-sifat pendukungnya
Proses-proses dalam termodika yaitu :
Isokhorik (Volume tetap)
Isobarik (Tekanan Tetap)
Isotermal/isotermik (Temperatur tetap)
Adiabatik
Persamaan Gas ideal :
[tex]\boxed{pV=nRT}[/tex]
Persamaan Usaha :
[tex]\boxed{W=p\Delta\:V}[/tex]
Persamaan Energi dalam :
[tex]\boxed{\Delta\:U=\frac{3}{2}nRT}[/tex] (monoatomik)
[tex]\boxed{\Delta\:U=\frac{5}{2}nRT}[/tex] (diatomik)
Persamaan kalor :
[tex]\boxed{Q=W+\Delta\:U}[/tex]
[tex]\boxed{Diketahui}[/tex]
Massa H₂ (m) = 1 gram
Suhu (T) =327°C
[tex]\boxed{Ditanya}[/tex]
Energi dalam gas H₂
[tex]\boxed{Penyelesaian}[/tex]
Energi dalam gas H₂ tersebut bisa dicari dengan menggunakan persamaan :
ΔU = 5/2 n R T
dimana :
n = m / Mr (Mr H₂ = 2 gram/mol)
n = 1 gram / 2 gram/mol
n = 0,5 mol
dan
R = 8,31 J/mol.K
T = 327°C + 273 = 600K
sehingga :
ΔU = 5/2 n R T
ΔU = 5/2 (0,5 mol) (8,31 J/mol.K) (600K)
ΔU = 6.232,5 J
ΔU = 6,2 kJ
Jadi besar energi dalam gas H₂ adalah 6,2 kJ.
[tex]\boxed{Kesimpulan}[/tex]
Besar energi dalam gas H₂ adalah 6,2 kJ.

12. What two sub-atomic particles are found in the nucleus of an atom?
Jawaban:
Neutrons and Protons
Penjelasan:
An atom is the smallest unit of ordinary matter that forms a chemical element. Every solid, liquid, gas, and plasma is composed of neutral or ionized atoms. Atoms are extremely small, typically around 100 picometers across. They are so small that accurately predicting their behavior using classical physics, as if they were tennis balls for example, is not possible due to quantum effects.
Every atom is composed of a nucleus and one or more electrons bound to the nucleus. The nucleus is made of one or more protons and a number of neutrons. Only the most common variety of hydrogen has no neutrons. More than 99.94% of an atom's mass is in the nucleus. The protons have a positive electric charge, the electrons have a negative electric charge, and the neutrons have no electric charge. If the number of protons and electrons are equal, then the atom is electrically neutral. If an atom has more or fewer electrons than protons, then it has an overall negative or positive charge, respectively – such atoms are called ions.
The electrons of an atom are attracted to the protons in an atomic nucleus by the electromagnetic force. The protons and neutrons in the nucleus are attracted to each other by the nuclear force. This force is usually stronger than the electromagnetic force that repels the positively charged protons from one another. Under certain circumstances, the repelling electromagnetic force becomes stronger than the nuclear force. In this case, the nucleus splits and leaves behind different elements. This is a form of nuclear decay.
The number of protons in the nucleus is the atomic number and it defines to which chemical element the atom belongs. For example, any atom that contains 29 protons is copper. The number of neutrons defines the isotope of the element. For example, a copper atom with 34 neutrons is copper-63 (29+34), and with 36 neutrons is copper-65; natural copper is about 70% Cu-63 and the rest is Cu-65. Atoms can attach to one or more other atoms by chemical bonds to form chemical compoundssuch as molecules or crystals. For example, New York City's Statue of Liberty was originally made of pure copper, but over the years, the surface combined with oxygen, carbon and sulfur atoms to make a green patina on the copper. The ability of atoms to attach and detach is responsible for most of the physical changes observed in nature. Chemistry is the discipline that studies these changes.

I hope this helps :)
Semoga Membantu :)
Jawaban:
Neutrons and Protons
Penjelasan:
Atom adalah suatu satuan dasar materi, yang terdiri atas inti atom serta awan elektron bermuatan negatif yang mengelilinginya. Inti atom terdiri atas proton yang bermuatan positif, dan neutron yang bermuatan netral (kecuali pada inti atom Hidrogen-1, yang tidak memiliki neutron). Elektron-elektron pada sebuah atom terikat pada inti atom oleh gaya elektromagnetik. Sekumpulan atom demikian pula dapat berikatan satu sama lainnya, dan membentuk sebuah molekul. Atom yang mengandung jumlah proton dan elektron yang sama bersifat netral, sedangkan yang mengandung jumlah proton dan elektron yang berbeda bersifat positif atau negatif dan disebut sebagai ion. Atom dikelompokkan berdasarkan jumlah proton dan neutron yang terdapat pada inti atom tersebut. Jumlah proton pada atom menentukan unsur kimia atom tersebut, dan jumlah neutron menentukan isotop unsur tersebut.

14. how do we know how to use the different transitions and conjuctions in the best place ?
transition markers are used after you end a sentence
example: i sleep. and then, i wake up.
conjuctions are the terms to assemble 2 or more different words in a specified context somehow like:
i like apple and orange.
i like apple but i hate orange.
