- Define a method computeGasVolume that returns the volume of a gas given parameters pressure, temperature, and moles. Use the gas equation PV = nRT, where P is pressure in Pascals, V is volume in cubic meters, n is number of moles, R is the gas constant 8.3144621 ( J / (mol*K)), and T is temperature in Kelvin. All parameter types and the return type are double.Write a method on elicpse, computeFutureValue, which receives the investment amount, annual interest rate and number of months as parameters and does the following: Prints the interest amount earned each month and the new value of the investment (hint: use a loop).
