The container is thrown on a fire, and its temperature rises to 700°C. What is the pressure at this temperature? 5) Consider a region of the atmosphere of volume 25 dm³, which at 20°C contains about 1.0 mol of molecules. Take the average molar mass of the molecules as 29 g mol and their average speed as about 400 m s. Estimate the energy stored as molecular kinetic energy in this volume of air. 6) What is the minimum energy that a bird of mass 25 g must expend in order to reach a height of 50 m? 7) The potential energy of a charge Qı in the presence of another charge Q2 can be expressed in terms of the Coulomb potential, P(phi): Q. V= Qi0 4те The units of potential are joules per coulomb, J C-", so when o is multiplied by a charge in coulombs, the result is in joules. The combination joules per coulomb occurs widely and is called a volt (V), with 1 V = 1 J C-!. Calculate the Coulomb potential due to the nuclei at a point in a LiH molecule located 200 pm from the Li nucleus and 150 pm from the H nucleus. (Hint: Use Q =+Ze, where Z is the atomic number and e is the elementary charge.) 8) Plot the Coulomb potential due to the nuclei at a point in a Na*Cl¯ ion pair located on a line half- way between the nuclei (the internuclear separation is 283 pm) as the point approaches from infinity and ends at the mid-point between the nuclei. 9) Determine the wavelength of the radiation used by an FM radio transmitter broadcasting at 92.0 MH-2. 11:02 AM a O Type here to search (3 2/4/2020
