The temperature at state A is 20°C, that is 293 K. What is the heat (Q) for process A to D, in MJ (MegaJoules)? (Hint: What is the change in thermal energy and work done by the gas for this process?) Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, is already given in the question statement. p (atm)

Hi, could I get some help with this macro-connection physics problem involving the Ideal Gas Law? The set up is: What is the average volume in nm3 (cubic nanometers) taken up by molecules of an ideal gas at room temperature (taken as 300 K), and 1 atm of pressure or 101325 N/m2 to 4 digits of precision if kB = 1.38e-23 J/K and 1 nm = 10-9 m? Thank you.
A container holds 102.9 liters of Oxygen at 268.4K and a pressure of 1.95 atmospheres. How much heat is required to raise the temperature of this gas to 314.1K, holding the volume constant? Give your answer in kJ. Treat the gas as an ideal gas. Note: It is understood that your answer is in units of kilo-Joules, however do not explicitly include units in your answer. Enter only a number. If you do enter a unit ("kJ" in this case), you answer will be counted wrong.
A 4.00-m-long cylinder of solid aluminum has a radius of 2.00 cm. 1)If the cylinder is initially at a temperature of 5.00∘C, how much will the length change when the temperature rises to 30.0°C? (Express your answer to three significant figures.) 2)Due to the temperature increase, by how much (in %) would the density of the aluminum cylinder decrease? (Express your answer to three significant figures.) 3)By what percentage does the volume of the cylinder increase? (Express your answer to three significant figures.)
If you have 4 moles of a diatomic ideal gas (such as oxygen or nitrogen), how much heat is required to raise the temperature of this gas from 269.5K to 288.3K if the volume of the gas remains constant during the heating? Note: It is understood that your answer is in units of Joules, however do not explicitly include units in your answer. Enter only a number. If you do enter a unit ("J" in this case), you answer will be counted wrong.

The pressure, volume, and temperature of a mole of an ideal gas are related by the equation PV = 8.31T, where P is measured in kilopascals, V in liters, and T in kelvins. Use differentials to find the approximate change in the pressure if the volume increases from 10 L to 10.6 L and the temperature decreases from 335 K to 330 K. (Note whether the change is positive or negative in your answer. I Round your answer to ti decimal places.
