Solids have a definite,fixed shape.. So option B which is the second checkbox ☑️ is the correct answer... l hope it helped :)
Answer:
If the container is cooled, the gas particles will lose kinetic energy and temperature will decrease.
If the gas particles move more quickly, they will collide more frequently with the walls of the container and pressure will increase.
If the gas particles move more quickly, they will collide with the walls of the container more often and with more force, and pressure will increase.
Explanation:
The temperature of gases is a measure of the average kinetic energy of the molecules. With increasing temperature comes more kinetic energy for the gaseous particles. If temperature of the system is reduced, the particles will have less kinetic energy and would not be able to move. Temperature is directly proportional to average kinetic energy.
Pressure of gases increases when there is more frequent collision between their particles. The usual case is for gases to move more rapidly as a result of increase in kinetic energy of the system. The particles collides more frequently with one another and the walls of the container if the kinetic energy is raised.
Answer: Your friend is incorrect.
Explanation: If we have an object or something that isn’t moving, (let’s say a notebook on a desk). If there is change, and the notebook moves, there is acceleration. Force = Mass times acceleration, f = m*a. There has to be a force, first of all. If you touched the notebook and moved it, some of your energy is transferred and now the notebook has kinetic energy. If our system is you and the notebook, the total energy doesn’t change. the energy is transferred, but doesn’t change. Your friend is not correct. Please give brainliest hope this helped!
