In a phase change, as temperature increases, the aberage kinetic energy does too. therefore particles move...
QUESTION 16 Which of the following is NOT an assumption made by the kinetic molecular theory? A gas is a collection of particles (molecules or atoms) in constant motion. This motion is straight-line motion The average kinetic energy (energy due to motion) of the gas particles is proportional to the temperature measured in kelvin. As temperature increases, the particles move faster and have more energy There is no attraction or repulsion between the gas particles, another wards, they not interact....
As the temperature of a gas increases, _______________. a. absolute zero increases b. the average kinetic energy of the gas particles increases c. the gas constant decreases d. its volume decreases e. its pressure decreases
11. When the volume of a gas increases at constant temperature: the average kinetic energy stays the sameB - the mean square velocity stays the same the frequency of collisions decreases the force per collision decreases Incorrect. Submit 12. When the moles of a gas increase at constant volume and tempera the average kinetic energy increases the mean square velocity stays the same - the frequency of collisions increases the force per collision increases Incorrect. Submit 13. When hydrogen gas...
How would a decrease in temperature affect the energy and movement of gas particles? A) The energy will decrease and the molecules will move at the same speed. B) The energy will increase and the molecules will move more slowly. C) The energy will increase and the molecules will move more quickly. D) The energy will increase and the molecules will move at the same speed. E) The energy will decrease and the molecules will move more quickly. F) The...
The average kinetic energy of the molecules in a gas sample depends only on the temperature, T. But given the same kinetic energies, a lighter molecule will move faster than a heavier molecule.R=8.314 J/(mol·K) and ℳ is molar mass in kilograms per mole. Note that a joule is the same as a kg·m2/s2.What is the rms speed of Cl2 molecules at 415 K? What is the rms speed of He atoms at 415 K?
Increasing the temperature of a reaction increases the rate of of reaction, why? Does it change the free energy of the transition state?
Which assumption is not part of the kinetic-molecular theory of gases? A. The kinetic energy of gas particles change with change in temperature. B. Because the space between gas particles is large, gas particles exert no attractive forces on each other. C. When gas particles collide with each other, they rebound and travel in new directions D. The size of gas particles is small compared to the space between the particles. E. Gas consists of particles that move randomly and...
Why does the pressure of a gas sample increase when the temperature is increased? Assume the volume remains constant. Select all that apply. Why does the pressure of a gas sample increase when the temperature is increased? Assume the volume remains constant. Select all that apply. Choose one or more: O A. The average kinetic energy of the gas increases as the temperature increases, causing more energetic collisions with the walls. O B. As the temperature of the gas increases,...
Question 33 Which statement is TRUE according to the kinetic molecular theory? The average kinetic energy of a particle is proportional to the temperature in Kelvin. The size of the particle is large compared to the volume. The collisions of particles with one another is not completely elastic. A single particle does not move in a straight line.
