You do an experiment in which you transfer energy to 1.2 moles of a gas and measure it’s change in temperature. You make a graph of the data as shown. The y-axis is the amount of energy added and the x-axis is the temperature. A) how many moles per molecule does this substance have? B) is the substance most likely a monatomic gas, diatomic or another type of gas?

The temperature of an ideal monatomic gas is increased from 25C to 50C. Does the average translational kinetic energy of each gas atom double? Explain. If your answer is no, what would the final temperature be if the average translational kinetic energy was doubled?

For a planet to have an atmosphere, gravity must be sufficient to keep the gas from escaping The escape speed a particle needs to escape the earth's gravitational attraction is 1.1 x 10 m/s. The motion of projectiles never depends on mass, so this escape speed applies equally to rockets and to molecules in the earth's upper atmosphere. Part A At what temperature does the rms speed of nitrogen molecules equal the escape speed? Express your answer in kelvins.

Consider a box divided into three parts and contains N gas molecules A) Write the formula for the multiplicity of any given configuration. B) Consider two configurations (i) A with equal molecules in all three thirds of the box (ii) B with equal number of molecules in each half of the box divided into two equal parts rather than three. Find the ratio of multiplicity of configuration A to the configuration B. C)  Find WA / WB for N=100, put 34 molecules into one of the three box parts of configuration A and 33 in each of the other two parts.   also want soltion all these part urgently  thanks
