How much heat is required to convert 20.0 g of ice at 50.0⁰C to liquid water at 0.0⁰C? The specific heat of ice is 2.06 J/(g∙⁰C)
Alex777 [14]

Answer:

8740 joules are required to convert 20 grams of ice to liquid water.

Explanation:

The amount of heat required (Q), measured in joules, to convert ice at -50.0 ºC to liquid water at 0.0 ºC is the sum of sensible heat associated with ice and latent heat of fussion. That is:

Q = m\cdot [c\cdot (T_{f}-T_{o})+L_{f}] (1)

Where:

m - Mass, measured in grams.

c - Specific heat of ice, measured in joules per gram-degree Celsius.

T_{o}, T_{f} - Temperature, measured in degrees Celsius.

L_{f} - Latent heat of fussion, measured in joules per gram.

If we know that m = 20\,g, c = 2.06\,\frac{J}{g\cdot ^{\circ}C}, T_{f} = 0\,^{\circ}C, T_{o} = -50\,^{\circ}C and L_{f} = 334\,\frac{J}{g }, then the amount of heat is:

Q = (20\,g)\cdot \left\{\left(2.06\,\frac{J}{g\cdot ^{\circ}C} \right)\cdot [0\,^{\circ}C-(-50\,^{\circ}C)]+334\,\frac{J}{g} \right\}

Q = 8740\,J

8740 joules are required to convert 20 grams of ice to liquid water.

A sample of carbon dioxide gas occupies a volume of 250 mL at 25c what volume will it occupy at 95c
anzhelika [568]

Considering the Charles's law, the sample of carbon dioxide gas will occupy 308.72 mL.

<h3>Charles's law</h3>

Charles's law establishes the relationship between the temperature and the volume of a gas when the pressure is constant. This law says that the volume is directly proportional to the temperature of the gas: for a given sum of gas at constant pressure, as the temperature increases, the volume of the gas increases and as the temperature decreases, the volume of the gas decreases.

Mathematically, Charles's law states that the ratio between volume and temperature will always have the same value:

\frac{V}{T} =k

Considering an initial state 1 and a final state 2, it is fulfilled:

\frac{V1}{T1} =\frac{V2}{T2}

<h3>Final volume in this case</h3>

In this case, you know:

  • V1= 250 mL
  • T1= 25 C= 298 K (being 0 C=273 K)
  • V2= ?
  • T2= 95 C= 368 K

Replacing in Charles's law:

\frac{250 mL}{298 K} =\frac{V2}{368 K}

Solving:

V2=368 K\frac{250 mL}{298 K}

<u><em>V2= 308.72 mL</em></u>

Finally, the sample of carbon dioxide gas will occupy 308.72 mL.

Using the combined gas law, if the volume of a gas at 155kPa changes from 22L to 10L. What is the new pressure if the temperatur
Deffense [45]

Answer:

The answer to your question is  P2 = 342 kPa

Explanation:

Data

Pressure 1 = P1 = 155 kPa

Volume 1 = V1 = 22 l

Pressure 2 = P2 = ?

Volume 2 = V2 = 10 l

Temperature = constant

Process

1.- Write the equation of the combined gas law

                 P1V1/T1 = P2V2/ T2

Cancel T1 and T2 because they measure the same

                 P1V1 = P2V2

-Solve for P2

                 P2 = P1V1/V2

2.- Substitution

                 P2 = (155 x 22) / 10

3.- Simplification

                 P2 = 3410 / 10

4.- Result

                 P2 = 342 kPa
