Which of the following true abut real gases?
1) Real gases have volume and experience intermolecular attractions; compared to an ideal gas, a real gas' observed pressure will be increased due to intermolecular forces and also increased due to the volume of the real gas particles. 2) Real gases have volume and experience intermolecular attractions; compared to an ideal gas, a real gas' observed pressure will be decreased due to intermolecular forces but increased due to the volume of the real gas particles. 3) Real gases have volume and experience intermolecular attractions; compared to an ideal gas, a real gas' observed pressure will be increased due to intermolecular forces but decreased due to the volume of the real gas particles. 4) Real gases have volume and experience intermolecular attractions; compared to an ideal gas, a real gas' observed pressure will be decreased due to intermolecular forces and also decreased due to the volume of the real gas particles. Only 1 answer is true. Thanks!
All of the following statements concerning gas molecules are true except?
Real molecules have a weak attraction for each other. Attraction is greater between fast-moving molecules than between slow-moving molecules. Real molecules occupy a finite space. Real molecules have the greatest attraction for each other at low temperatures. Real molecules have the greatest attraction for each other at high pressures.
Which of the following statements regarding gases is false?
a) a real gas molecule is by definition larger than an ideal gas molecule b) real gas molecules exert attractive forces toward one another whereas ideal gas molecules do not c) for both real and ideal gases, the volume and temperature of a sample at constant pressure are inversely related d) at a given temperature, the average kinetic energies of He atoms and Cl2 molecules are the same e) C and D
Which statement is not true about a real gas?
C, as all collisions are elastic. Basically, any elastic collision is not influenced by a force (attraction) thus there is no change in potential. Of course real gasses are not perfectly elastic so the IDEAL gas law is only an approximation. Thus, the answer is C.
Complete the following: Because real gas particles have attraction for one another:?
3. Real gases act more ideally at higher temperatures and lower pressures. Real gases have higher kinetic energy (energy of motion) at higher temperatures. At lower pressure they have much more free space and don't bump into one another very often. The combination of high temperature and low pressure makes real gases follow the mathematical rules of an ideal gas.
Chemistry Question about Real Gases?
Which of the following statements is true for real gases? Choose all that apply. Attractive forces between molecules cause a decrease in pressure compared to the ideal gas. The volume occupied by the molecules can cause a decrease in pressure compared to the ideal gas. As attractive forces between molecules increase, deviations from ideal behavior become more apparent at relatively high temperatures. As molecules increase in size, deviations from ideal behavior become more apparent at relatively high pressures.
