Question

嘿伙计们，我完全迷失在这个python作业问题上的问题是定义一个函数compute_gas_volume，它返回给定参数压力，温度和摩尔数的气体体积。使用气体方程式PV = nRT，其中P是以帕斯卡为单位的压力，V是以立方米为单位的体积，n是摩尔数，R是气体常数8.3144621（J /（mol * K）），T是以开尔文为单位的温度

首发代码是

gas_const = 8.3144621
def compute_gas_volume((gas_pressure,,gas_temperature,gas_moles):

    gas_pressure = 100.0
    gas_moles = 1.0
    gas_temperature = 273.0
    gas_volume = 0.0
    gas_volume = compute_gas_volume(gas_pressure, gas_temperature, gas_moles)
print('Gas volume:', gas_volume, 'm^3')

任何人都可以帮我解决这个问题吗？

Answer 1

由于法则是PV = nRT，体积可以简单地计算为V = nRT / P，因此：

GAS_CONST = 8.3144621
def compute_gas_volume(gas_pressure, gas_temperature, gas_moles):
    return gas_moles * GAS_CONST * gas_temperature / gas_pressure

Answer 2

将其重新排列为等于V：

private static readonly Random Rnd = new Random();

private static void Main()
{
    // Initialize all moves to false
    bool[] allMoves = new bool[64];
    for (int i = 0; i < allMoves.Length; i++) allMoves[i] = false;

    // Pretend a move was made and set some to true
    allMoves[0] = true;
    allMoves[3] = true;
    allMoves[5] = true;

    // Get ALL indexes of 'false' items (currently everything except 0, 3, and 5)
    var validIndexes = GetIndexesOfFalseItems(allMoves).ToList();

    // Choose a random item from that list
    var randomValidIndex = validIndexes[Rnd.Next(validIndexes.Count)];

    // Now we get our next move from our main list at that index
    var nextMove = allMoves[randomValidIndex];

    // Rest if game code...
}
