1)two rigid tanks of equal size and shape are filled with different gases. the tank on the left contains oxygen, and the tank on the right contains hydrogen. assume both gases are ideal. the molar masses of oxygen and hydrogen are 32 and 2, respectively. both containers are at the same temperature. a pressure gauge is pin oxygen hydrogen connected to each tank. both gauges show a reading of 230 kpa.
is the number of oxygen molecules in the left container greater than, less than, or equal to the number of hydrogen molecules in the right container? explain your reasoning.
2) a cylindrical pump contains one mole of an ideal gas. the piston is free to move, but no gas can enter or leave the pump. neglect friction between the piston and the cylinder walls.
the piston is quickly pressed inward as shown in the diagram. a sensor in the pump records an increase in temperature.
a. how can you account for the increase in temperature of the gas? explain.
b. did the thermal energy of the gas increase, decrease, or remain the same in this process? explain.

The chart shows the costs and shipping times for materials that a company needs to build a new product. which describes the best trade-off if the company needs to start building their product within the next two years? they should order the domestic materials because it is always best to choose the fastest shipping time. they should order the imported materials because it is always best to choose the lowest cost for materials. since the shipping time is longer, they should order the domestic materials because the additional cost is worth it to get the materials in time. even though the shipping time is longer, they should order the imported materials because they are less expensive and should arrive in plenty of time to build the product.

1. what is the relationship between wavelength and the penetrating power of an electromagnetic wave? a) the penetrating power has no relationship to the wavelength. b) the penetrating power increases as the wavelength increases. c) the penetrating power decreases as the wavelength increases. d) the penetrating power decreases as the wavelength decreases. 2. as ice melts and turns into water, the speed of sound through the material would most likely do what? justify your answer. a) the speed would not change because the material is always water. b) the speed of sound would increase because the density of water is less than that of ice. c) the speed of sound would increase because energy is added to ice in order to make it melt. d) the speed of sound would decrease because sound travels faster through solids than liquids. 3.which of these waves need a medium to travel through? a) sound b) x-rays c) infrared rays d) visible light
