Show that one mole of any gas occupies a volume of 22.4 L at 1 atm and 0°C i. e., at standard temperature and pressure (STP). [Given: R = 0.0821 L. atm/mol. K] on T 1 . 1 (b) A tank of volume 0.3 m contains 2 moles of oxygen gas at 20°С. Find the average K. E. per atom and also find the rms speed of the atoms. [Given: k = 1.38 x 10-23 J/K; R= 8.317 J/mol, M= 16 g/mol]

Calculate the amount of heat produced when 18000 coulombs of charge is transferred in one hour through a potential difference of 50v

Which describes increasing the efficiency of energy resource

Isobars are lines of constant or equal pressure on a weather map. they can be used to find areas of low or high pressure over a broad area, and they can tell us how intense the system may be. on weather maps, you may have noticed areas that have a large l or h over a region with lines circling around them. the l stands for low pressure and h stands for high pressure. the lines circling them are isobars. check out the pressure system and isobars over georgia and florida. what is the present weather in this area ? a) clear and sunny b) cold and cloudy c) changing weather d) lots of precipitation
