Complete the energy profile diagram and state whether the reaction is endothermic or exothermic, explain your answer. 10.What are the units for enthalpy change, ΔH
Steam tables contain specific volume, enthalpy, internal energy, and entropy of water (both liquid and vapor) over a range of temperatures and pressures, including at saturation and supercritical conditions.
Enthalpy, Energy, Heat Worksheet. 1. Two beakers of water, one containing 50 mL and the other containing 250 mL, are heated to 75°C. Using these beakers as your examples, explain the difference between heat and temperature. 2. A quantity of gas was cooled from 323 K to 273 K. Express this temperature difference in degrees Celsius and Kelvins.
The specific heat capacity of zinc is 0.389 J K-1 g-1, and that of water near 100°C is 4.22 J K -1 g -1 . Calculate the final temperature reached by the zinc and the water.
Figures and tables showing how the properties of water changes along the boiling/condensation curve (vapor pressure, density, viscosity, thermal conductivity, specific heat, Prandtl number, thermal diffusivity, entropy and enthalpy).
Instructional video. This simulation shows an enthalpy-entropy (H-S) diagram for water. Use the checkboxes to display lines of constant pressure P (purple), temperature T (green) or vapor quality q (blue).
This simulation shows a pressure-enthalpy (P-H) diagram for water. Check and uncheck the boxes to add or remove a property from the diagram. You can show lines of constant vapor quality q (blue), temperature T (red), density ρ (gold) and entropy S (purple).
