- Determine D for (a) He and (b) Xe at standard pressure and 0.0°C. Use d 5 2.65 and 4.00 Å, respectively. Answer to (a): 0.844 cm^2/sarrow_forwardwhere m stands for the mass of the particle, v stands for the particle speed, T stands for the Temperature of the system, and k stands for the Boltzmann constant. What would be the relative average kinetic energies for the helium, neon, and argon at 100K? (think about what this would mean for each variable) Explain how you assigned the relative positions of each gas.arrow_forwardThe following values are found for the speed of sound in air:Temperature (°C) 20 100 500 1000Speed (m/sec) 344 386 553 700Compare these values to the vrms speeds of N2 moleules at these temperatures.arrow_forward
- please don't round off util the final answers. Determine the Boyle temperature of hydrogen. Pc = 13.13 bar, TC = 33.19Karrow_forwardAt what point is the temperature in F exactly twice that in C?arrow_forwardThe compression ratio in an automobile engine is the ratio of the gas pressure at the end of the compression stroke to the pressure in the beginning. Assume that compression occurs at constant temperature. The total volume of the cylinder in an automobile is 350 cm3, and the displacement the reduction in volume during the compression stroke is 309 cm3. What is the compression ratio in that engine?arrow_forward
- Show the relationship between two variables, Ea and ΔHo ?arrow_forward5. Methane (CH4) at 57°C and 702 mmHg has a density x g/L. What is the value of x?arrow_forwardCalculate the mean speed of atoms of argon in a gas at 25 oC if the mean speed of neon under these conditions is 560 m s-1. B) What is the ratio of kinetic energies of argon and neon atoms at this temperature ?arrow_forward
- THERMOCHEMISTRY 1. State Boyle's Law and Charle’s Law respectively with their corresponding mathematical expression 2. Predict on the basis of the two laws the effect of changing the pressure and the temperature on the volume of a given mass of gasarrow_forwardDescribe in your own words the Kinetic Molecular Theory of gases. The Kinetic Molecular Theory of gases tells us that the energy content of any gas is related only to its temperature. It also tells us that it is possible to compute the "RMS" (root mean squared) velocity of any gas molecule if you know its formula weight and its temperature. Using this information describe how you might compute the RMS velocity of sulfur dioxide (SO2) in the atmosphere of the planet Venus (T = 820 F), the RMS velocity of oxygen (O2) in the atmosphere of Earth (T = 50 F), or the RMS velocity of carbon dioxide (CO2) in the atmosphere of Mars (T = - 80 F).arrow_forwardsmoke particles in air typically have masses of the order of 10^-16 kg. The rapid, irregular motions of these particles caused by collisions with air molecules can be observed with a microscope. Assume a particular type of smoke particle has a mass of 3.00 x10^-16 kg and is in a room with a temperature of 300 K. a) if instead you were considering a hydrogen gas molecule (m= 3.34x10^-26 kg) at 300 K, would the average translational kinetic energy be larger than, smaller than or equal to that of the smoke particle? b) would the rms speed of the hydrogen atom be larger than, smaller than, or equal to that of the smoke particle?arrow_forward
