||Popup Periodic Table
Retrieve atomic numbers, atomic weights, melting points, boiling points, common oxidation states, and
notes on the appearance of each element as you select elements from this simple periodic table.
downloaded and used offline.
GraphPad builds a simple graph from your laboratory data and emails
a GIF file to you for inclusion in your reports or Web pages. Simple
linear regression is included.
||Gas Law Calculator
Solve the ideal gas, van der Waals, and Dieterici equations
of state for pressure, volume, temperature, or moles in a variety of convenient
units. Semiempirical parameters are computed from critical point data- a
database of common gases is included in the script, but you can input your
own critical point data if you wish. The Boyle temperature and the critical
compressibility factor are computed for the semiempirical equations, as well.
||Water Vapor Pressure/ Oxygen Solubility Calculator
A quick DO calculator based on empirical functions for oxygen solubility
taken from Standard Methods for Waste and Wastewater Analysis. Enter
the barometric pressure in torr, and the water temperature in °C. Hit
the Calculate button to see the saturated water vapor pressure and the
predicted DO concentration.
||Water Properties Calculator
Calculates the density, specific heat, and vapor pressure of pure, air-free
water at 1 atm for temperatures from 0°C to 100°C, using 5-point
Lagrange interpolation from data tables.
