How does the ideal gas law help in understanding the pressure and temperature changes during an explosion?

PV = nRT. where P is the pressure, V is the volume, n is the number of moles of substance in that volume, R is a constant known as the "Universal Gas ... The total volume V of the system is constant. n = nAr + nO = PV/(RT) Since ... Therefore (RT/V)dV = (R/2)dT, or 2dV/V = dT/T, or V2/T = const ... P = n (RT/V). At constant temperature and volume the pressure of a gas is ... once again R and n have not changed, and now not even T has not changed so ... p = pressure in pascals (unit Pa) · V = volume in cubic metres (m3) · n = moles of gas (mol = mass in g / molecular mass of gas Mr) · R = ideal gas constant = ... R is the gas constant = 8.314 J K-1 mol-1. T is temperature in K. The gas law ... (c) Put the values into the equation n = PV / RT: n = (200,000 × 0.01) ... By Gay Lussac's law, V ∝ T, at constant pressure. This gives PV = RT, where R is a constant called universal gas constant. If the volume V contains n moles, the ... May 6, 2024 ... Collectively, these laws form the ideal gas law equation: PV=nRT. where P is the pressure, V is the volume, n is the number of moles of gas, R ... ... r for a period of t years is. FV = PV + INT = PV(1 + rt). We can also solve for the present value PV to obtain. PV = FV/(1 + rt). Examples. 1. For a 8.5% simple ... Nov 21, 2023 ... ... R and the mass of the gas expressed in moles n. Performing a little algebra, we obtain the more familiar form: \LARGE pV=nRT. A three ... PV = Present value; FV = Future value; r = Rate of interest (percentage ÷ 100); n = Number of times the amount is compounding; t = Time ...
