please help me solve the following general physics questions. Questions are ideal gas and kinetic theory

6. Suppose there are two identical gas cylinders. One contains the monatomic gas helium (He), and the other contains an equal mass of the monatomic gas neon (Ne). The pressures in the cylinders are the same, but the temperatures are different. Determine the ratio KEye/KEe Of the average kinetic energy of an atom of helium to the average kinetic energy of an atom of neon. 7. A gas, while expanding under isobaric conditions, does 420 ] of work. The pressure of the gas is 1.30 x 10 pa, and its initial volume is 1.20 X 103 m3. What is the final volume of the gas? m3 8. Two moles of an ideal monatomic gas are at a temperature of 325 K. Then, 2210 J of heat is added to the gas, and 880 ] of work is done on it. What is the final temperature of the gas? K 9. A monatomic ideal gas expands from point A to point B along the path shown in the figure. Determine the work done by the gas.(The vertical axis is marked in increments of 1.00 x 10 Pa and the horizontal axis is marked in increments of 1.50 m3.) J Pressure w Volume 10. Suppose 1.10 x 102 moles of a monatomic ideal gas undergoes an isothermal expansion as shown in the figure. (The horizontal axis is marked in increments of 10 m3 and the vertical axis is marked in increments of 100 kPa.) How much. How much work is done by the gas from (A) to (B)? J
