A sample of 5.0 mol CO2(g) is originally confined in 15 dm3 at 280 K and then undergoes adiabatic expansion against a constant pressure of 78.5 kPa until the volume has increased by a factor of 4.0. Calculate q, w, delta T, and delta U, and delta H. (The final pressure of the gas is not necessarily 78.5 kPa.) If the enthalpy you calculate does not equal -4.5 kJ and the temperature change - 24 K, you made a mistake.

A sample of 1.3 mol of CO2 (g) is placed in a 5.0 L rigid container at an initial temperature is 300 K. When 6.98 kJ of heat is added to the system (at constant volume), the temperature rises to 353 K. Calculate q, w, ∆U, ∆H, and CV. The molar heat capacity of O2(g) at constant pressure, is 31.2 J/(K mol) around room temperature. 2.5 mol of O2(g) is heated at constant pressure from 265 K to 310 K....

An engine using 1 mol of an ideal gas initially at 22.3 L and 454 K performs a cycle consisting of four steps: 1) an isothermal expansion at 454 K from 22.3 L to 40 L ; 2) cooling at constant volume to 270 K ; 3) an isothermal compression to its original volume of 22.3 L; and 4) heating at constant volume to its original temperature of 454 K . Find its efficiency. Assume that the heat capacity is...

A piston is filled with 75.0 mol of an ideal gas at a pressure of 3.40x10Pa at a temperature of 1250 K. While keeping the pressure constant, the volume of the piston is reduced to 0.530 m. The gas is then allowed to expand slowly while keeping the temperature constant until the volume reaches 4.16 m2 The gas is then compressed rapidly until the gas reaches its original state. Complete the chart below. Do not include units in your...
