### Description

Boyle Charles Calculator is a calculation sheet that solves a gas problem of volume, pressure, and temperature. This Boyle Charles Calculator is a subset of iPad Mol Calculator software. A typical problem is as follows. (Example) There is 0.05 mol of hydrogen gas. (1)When the temperature is 20 ℃ and the pressure is 1 atmosphere, how much liters is the gas ? (2)When the temperature is 20 ℃ and the gas is packed in a 0.1-liter container, how much is the pressure of hydrogen gas? (1)Volume calculation Boyle Charles Calculator solves the problem in the following three steps. //Step 0: Preparation// Gather known data. //Step 1: Definition// Enter known data into the BC sheet. Mol = 0.05, T = 20[C], p = 1[atm] //Step 2: Calculation// Data are not independent but mutually related by formulae. Calculation is a conversion from unknown data to known data using the formulae. The formulae are embedded in P and G buttons. Touching out those buttons executes the formulae and changes unknown data to known data. Touch out buttons as follows. Touch out P_Mol button. StdVol and Vol data are changed to known data. It turns out that the volume of hydrogen gas is 1.2 L. (1)Pressure calculation //Solution by V1.00// Use the above results. Enter the following data Vol = 0.1[L] Touch out G_Pres button. Pressure data are changed to known data. It turns out that the gas pressure is 12.02 atmospheres. //Solution by V2.00// Change PresVol mode to pressure mode. //Step 1: Definition// Enter the following data. Mol = 0.05, T = 20[C], Vol = 0.1[L] //Step 2: Calculation// Touch out P_Mol button. StdVol and Pres data are changed to known data. It turns out that the gas pressure is 12.02 atmospheres. [Data label] n [mol]: Mol quantity of substance. StdVol [L]: Gas volume of substance at 0 deg C and 1 atm. T [C][F]: Temperature. p [atm][kPa][mmHg]: Pressure Vol [L]: Gas volume of substance at the temperature T and at the pressure p. [Buttons and data] //P button and P data group// P (put) button inputs data to which the P button is assigned. P data group is a group of data to which the P buttons are assigned. The P data group has a special character. When one P data is input, all other data of the P data group are updated by formulae. //G button// G (get) button gets data from other data using formulae. //C butto// C (Clear) button clears all data. //PresVol button// Either pressure data or volume data belongs to P button data group. The PresVol button specifies pressure mode or volume mode. [Color change] Color change shows what data are input, output, or referenced data in this button execution. Input data:Blue color Referenced data:Yellow color Output data:Green color Uncalculated data:Red color [Formulae] Embedded formulae are as follows. StdVol = 22.414 x n StdVol /273.15 = p x Vol / (T + 273.15)
