- So each four dot shows four different states for an ideal gas. P is the pressure and the other one is the density of the gas. Is temperature of state 1 less or greater than the state 2? Can you please explain why?Learning Goal: To understand the ideal gas law and be able to apply it to a wide variety of situations. The absolute temperature T, volume V, and pressure p of a gas sample are related by the ideal gas law, which states that PV = nRT Here n is the number of moles in the gas sample and R is a gas constant that applies to all gases. This empirical law describes gases well only if they are sufficiently dilute and at a sufficiently high temperature that they are not on the verge of condensing. In applying the ideal gas law, p must be the absolute pressure, measured with respect to vacuum and not with respect to atmospheric pressure, and I must be the absolute temperature, measured in kelvins (that is, with respect to absolute zero, defined throughout this tutorial as -273°C). If p is in pascals and V is in cubic meters, use R = 8.3145 J/(mol · K). If p is in atmospheres and V is in liters, use R = 0.08206 L atm/(mol-K) instead.

When the metal cylinder transfers its energy to the water in the calorimeter, mechanical work is done since the metal will contract upon cooling. Prove that this work is truly negligible in comparison to the energy transferred for each of the materials used in this experiment. Since the pressure of the system is constant,. For the metals,. Use standard atmospheric pressure, 1.013 N/m², in your calculations, and the provided expansion coefficients. Material Aluminum Brass Copper Steel , Volume Expansion | Coefficient 0 75 56 50 51
