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.

You notice a very one-dimensional-thinking snail crawling along one rail of a railroad track. naturally, you remove it to a safer place. but before you do, you observe it as it moves from position xi = -92.9 cm to position xf = -64.9 cm along the rail, as measured from a point where one rail abuts the next. what is the snail\'s displacement δx in centimeters?

Did the proton move into a region of higher potential or lower potential? did the proton move into a region of higher potential or lower potential? because the proton is a negative charge and it accelerates as it travels, it must be moving from a region of higher potential to a region of lower potential. because the proton is a negative charge and it accelerates as it travels, it must be moving from a region of lower potential to a region of higher potential. because the proton is a positive charge and it slows down as it travels, it must be moving from a region of higher potential to a region of lower potential. because the proton is a positive charge and it slows down as it travels, it must be moving from a region of lower potential to a region of higher potential. request answerpart bwhat was the potential difference that stopped the proton? express your answer with the appropriate units.î”v î” v = nothingnothingrequest answerpart cwhat was the initial kinetic energy of the proton, in electron volts? express your answer in electron volts. ki k i = nothing ev request answerprovide feedback

When temperature of a substance increases, of its particles increase resulting in more between particles. real world applications of thermal expansion absolute zero (-273 degrees c) is the lowest possible temperature on the kelvin scale. it is a measure of where a substance has no kinetic energy. heat is a process of the . energy flows spontaneously from a object to a until equilibrium is reached. heat is measured in heat is transferred throughis a method of heat transfer that occurs between particles of matter that are in direct contact with each other. are poor conductors that impede / reduce the rate of heat transfer. is a method of heat transfer that occurs in fluids (non-solids) by means of currents. real world application of convectiona method of heat transfer through electromagnetic waves. when energy moves from one object to another inside a closed system, no energy is or in the system in the transaction. systems will spontaneously move to a state of organized energy or high disorder over time called
