Question 1 (2 points)
natulia [17]

Temperature is the average kinetic energy of gas molecules.

<h3>What is absolute zero?</h3>

The term absolute zero refers to the hypothetical point where the energy of molecules is zero. It is the point where all of their motion stops completely.

In a liquid, the movement of the molecules is more significant than in a solid. If you keep increasing the temperature of a liquid, it will boil and become a gas.

Matter contains energy which depends on the temperature of matter. To remove the energy of matter, you have to lowering its temperature.

The addition of energy to matter occurs when matter is heated. Hence, you add energy to matter by heating it.

The molecules at warm temperatures differ from the molecules at cool temperatures because the molecules at warmer temperatures move around more.

The air on a hot day compares to the air on a cool day in the sense that on a hot day, air molecules have more energy.

Temperature is depends on the kinetic energy of molecules. Hence, the best description of temperature is motion of molecules.

The temperature of a body is the average kinetic energy of its molecules.  When two things that are not touching have the same temperature their molecules move at the same average speed.

Since a liquid receives energy when it is heated, when the liquid is boiled beyond its boiling point, It will become a gas.

The difference between heat and temperature is that temperature measures the motion of molecules, and heat is the energy of that motion.

How many grams of O2(g) are needed to completely burn 46.0 g C3H8(g)?
Veronika [31]

Answer:

167,3 grams of O2 (g)

Explanation:

According to the following balanced equation:

C3H8 + 5 02 ---> 3 CO2 + 4 H20

We calculate the mass of the moles:

5 mol O2 = 16grams/mol x2x 5= 160 grams/mol

1 mol C3H8= 3 x12 grams/mol + 8 x 1 gram/mol= 44 grams/mol

If 44 grams C3H8 react with--------- 160 grams O2

46 gramsC3H8 react with    --------X = (46x160)/44 =167, 3 grams O2

How many miles of a gas sample are in a 20.0 l container at 373kand 203 kpa? the gas constant is 8.31 l-kpa/m-k
ladessa [460]
To simplify our solution for this probelm we first assume that the gas we are dealing with is an ideal gas. Given that it is ideal we can proceed the solution using the formula: PV=nRT where P is pressure (203KPa), V is volume (20.0 L), n is moles (required), T is absolute temperature (373K) and R is the gas constant ( <span>8.31 l-kpa/m-k). Plug in the given to the respective variables and you should get 3.28 moles of the gas sample. </span>
