1) A 3.00-mol sample of an ideal diatomic gas in which the gas particles both translate and rotate is initially at 600 K. Energy is then added thermally to the sample until its temperature is 1000 K. Assume that at the temperatures higher than 1000 K, the particles also vibrate, at the temperatures lower than 1000 K, the particles do not vibrate. The sample is then heated to 1200 K. Part A:- How much thermal energy does the sample absorb?...

4-/6.25 points My Notes SerCP10 12.P.023. An ideal monatomic gas is contained in a vessel of constant volume 0.260 m3. The initial temperature and pressure of the gas are 300 K and 5.00 atm, respectively. The goal of this problem is to find the temperature and pressure of the gas after 22.0 kJ of thermal energy is supplied to the gas. (a) Use the ideal gas law and initial conditions to calculate the number of moles of gas in the...

Calculate the rate of energy loss due to thermal radiation from an unclothed person if the average skin temperature is 37 °C and the room temperature is 20 °C. You may sume a total surface area of 1.5 m and a skin emissivity value of 0.9. How much energy (from food) must be consumed per day to compensate for this loss? If the person is surrounded by a layer of insulation of thickness 1.0 cm with a thermal conductivity of...
A cylinder contains 9.8 moles of ideal gas, initially at a temperature of 119°C. The cylinder is provided with a frictionless piston, which maintains a constant pressure of 7.4 × 105 Pa on the gas. The gas is cooled until its temperature has decreased to 27°C. For the gas CV = 14.41 J/mol ∙ K, and the ideal gas constant R = 8.314 J/mol · K. (a) Find the work done by (or on) the gas during this process. Is...
