Electron requires energy to move from ground state to excited state(higher energy levels). Hence option 1 is correct. Hope this helps!
Answer: will be five times higher
If 4 moles of gas are added to a container that already holds 1 mole of gas, the pressure inside the container
will be five times higher due to the change in the amount of gas.
Explanation:
4 moles of gas + 1 mole of gas = 5 moles of gas.
Also, the ideal gas equation pV = nRT
show that pressure is directly proportional to number of moles; so, if 1 mole of gas contains molecules that move randomly and freely under pressure inside the container; addition of 4 extra moles will sum up to 5moles of gas molecules moving randomly under pressure, and that is five times higher as well.
C the South Pole gets 24 hours of daylight
I believe the correct answer from the choices listed above is option B. Sugar stirred in tea <span> is an example of a solution. A solution is a mixture that exhibits homogeneous properties all throughout the mixture. Hope this answers the question. Have a nice day.</span>
