Given that the volume and amount  of water are kept constant,
P/T = constant
P₁/T₁ = P₂/T₂
Normal atmospheric pressure is 746 mmHg and normal boiling point of water is 100 °C.
746/100 = 589/T₂
T₂ = 79.0 °C

Calculate the hfg and sfg of steam at 120oC from the Clapeyron equation, and compare them to the tabulated values.
den301095 [7]

Answer:

The tabulated values at 120 C of <u><em>hfg = 2202.1</em></u><u> kJ/Kg </u>and <u><em>sfg </em></u><u>= 5.6 </u>

<u>kJ/Kg.K</u>

Explanation:

According to Clapeyron Equation :

h_{fg}=TV_{fg}\left (\frac{\partial P}{\partial T}  \right )_{sat}

=T(V_{g}-V_{f})_{120^{0}}\left ( \frac{\Delta P}{\125^{0}-115^{0}} \right )

Taking P2 at temperature 125 and P1 at 115 degree Celsius .

T = 120 + 273.15 = 393.15 K

P2 = 232.23 kPa and P1 = 169.18kPa

(these are experimental values given in the Data)

= 393.15(0.88133 -0.001060\ m^{3}/Kg)\frac{232.23-169.18 kPa}{10}

h_{fg} = 2206.8 kJ/Kg

S_{fg}=\frac{h_{fg}}{T}

\frac{2206.8}{393.15}

= 5.6131 kJ/Kg.K

The tabulated values at 120 C of <em>hfg = 2202.1</em> kJ/Kg and <em>sfg </em>= 5.6131

kJ/Kg.K

What type of solid is candle wax? Pls explain
kolbaska11 [484]
<span>the type of solid of the candle wax is amorphous.

 as the amorphous is doesn't melt at a certain temperature . and it is amorphous because it gets softer and softer and it doesn't melt at a certain temperature. so the wax shape change and being softer and when it re-cooled its shape will become harder again, without melting at distinct temperature.</span>

What type of reaction is required to bind two molecules of glycine together and release a molecule of water?​?
bulgar [2K]
<span>The glycine molecules can bind together and release a molecule of water by the process of condensation. Water would then be considered a by-product of the reaction. Condensation can also be seen when water in the air touches a container filled with cold liquid and you see water drops on the side of the glass.</span>
