Explanation:

What term describes the temperature at which a substance can change state from a liquid to a gas?
A. Boiling point
B. Melting point
C. Freezing point
D. Specific heat

Answers

Option A. Boiling point.

Explanation:

When you heat the water, the water gets converts into gaseous form.

As you know that water is in liquid form. So, when you heat the water, the water molecules absorbs the heat and get dispersed from one another molecules. i.e., molecules go far from the other molecules as they absorbed heat.

The term describes the temperature at which a substance can change state from a liquid to a gas, is boiling point. Therefore, option A is correct.

What is boiling point ?

The temperature at which a liquid's vapor pressure equals the pressure around it and the liquid transforms into a vapor is known as the boiling point of a substance. A liquid's boiling point varies depending on the atmospheric pressure in the area.

Boiling point and saturation temperature are synonyms. Sometimes the measurement's pressure serves as a definition for the boiling point. The International Union of Pure and Applied Chemistry was founded in 1982.

The boiling point of a sample can be calculated using a number of techniques, such as distillation, reflux, and a Thiele tube. The simplest approach makes use of a Thiele tube and has the benefit of requiring less than 0.5mL of substance.

Thus, option A is correct.

Show your work.

Answers

Answer:

6.75 sym.

Explanation:

Boyle's Law:  The pressure of a gas in an enclosed container with a flexible volume is inversely proportional to the volume occupied by the gas.

Empirically => P ∝ 1/V => P = k(1/V) => k = P·V

For any conditions of Pressure & Volume, Pressure x Volume is a constant.

Therefore, k₁ = k₂ => P₁V₁ = P₂V₂ => V₂ =  P₁V₁ / V₂

=> V₂ = (3atm)(0.450L)/(0.200L) = 6.75 atm.

Gas is confined in a metal tank in the figure. At 20.20°C, the gas exerts a pressure of 8.532 atm.
After heating the tank, the pressure of the gas increases to 10.406 atm. What is the temperature of
the heated gas?

Answers

Answer:

The temperature of  the heated gas is 357.6 K (or 84.6 C)

Explanation:

Gay Lussac's law indicates that, as long as the volume of the container containing the gas is constant, as the temperature increases, the gas molecules move faster. Then the number of collisions with the walls increases, that is, the pressure increases. That is, the pressure of the gas is directly proportional to its temperature.

In short, when there is a constant volume, as the temperature increases, the pressure of the gas increases. And when the temperature is decreased, the pressure of the gas decreases.

So, this law indicates that the quotient between pressure and temperature is constant:

[tex]\frac{P}{T} =k[/tex]

You want to study two different states, an initial state 1 and a final state 2. Then it is true:

[tex]\frac{P1}{T1} =\frac{P2}{T2}[/tex]

In this case:

P1= 8.532 atmT1= 20.20 C= 293.2 K (being 0 C= 273 K)P2= 10.406 atmT2= ?

Replacing:

[tex]\frac{8.532 atm}{293.2 K} =\frac{10.406 atm}{T2}[/tex]

Solving:

[tex]T2*\frac{8.532 atm}{293.2 K} =10.406 atm[/tex]

[tex]T2=10.406 atm*\frac{293.2 K}{8.532 atm}[/tex]

T2= 357.6 K

The temperature of  the heated gas is 357.6 K (or 84.6 C)

The new temperature of the heated gas when the pressure increase to 10.406 atm is 84.60 °C

Data obtained from the question Initial temperature (T₁) = 20.20°C = 20.20 + 273 = 293.20 KInitial pressure (P₁) = 8.532 atm Volume = constant New pressure (P₂) = 10.406 atmNew temperature (T₂) =?

How to determine the new temperature

The new temperature of the gas can be obtained by using the combined gas equation as illustrated below:

P₁V₁ / T₁ = P₂V₂ / T₂

Since the volume is constant, we have:

P₁ / T₁ = P₂ / T₂

8.532 / 293.20 = 10.406 / T₂

Cross multiply

8.532 × T₂ = 293.20 × 10.406

Divide both side by 8.532

T₂ = (293.20 × 10.406) / 8.532

T₂ = 357.6 K

Subtract 273 from 357.6 K to express in degree celsius

T₂ = 357.6 – 273

T₂ = 84.60 °C

O Boyle's Law
O Charles' Law
O Gay-Lussac's Law
Avogadro's Law

Answers

Answer:

Avogadro's Law; 15.1L

Explanation:

Boyle's Law- Pressure and volume are inversely related, so an increase in pressure= decrease in volume. We see this in the equation P1V1=P2V2.

Charle's Law- Gas expands/increases in volume when temperature increases, so they are proportional. We see this in the formula [tex]\frac{V1}{T1} = \frac{V2}{T2}[/tex].

Guy-Lussac's Law-  As temperature increases, pressure increases, so they are proportional. We see this in the formula [tex]\frac{P1}{T1} = \frac{P2}{T2}[/tex].

Avogadro's Law- There are equal amount of volume have an equal amount of moles, so they are proportional. We see this in the formula [tex]\frac{V1}{n1} = \frac{V2}{n2}[/tex].

Plugging in the values based on Avogadro's Law, we'll have:

[tex]\frac{36.5}{2.9} = \frac{V2}{1.2}[/tex]

12.6 = [tex]\frac{V2}{1.2}[/tex]

12.6 x 1.2 = V2

15.1L =V2

Answer:

v = 1.5 m/s

Explanation:

Given that,

Distance covered by a person, d = 105 m

Time taken, t = 70 s

We need to find the average speed of the person. We know that the average speed is given by :

[tex]v=\dfrac{d}{t}\\\\v=\dfrac{105\ m}{70\ s}\\\\v=1.5\ m/s[/tex]

So, the average speed of the person is equal to 1.5 m/s.
