Answer: Option (b) is the correct answer.
Explanation:
When the cake is baked then due to the heat provided to it there will occur movement of its molecules.
As a result, molecules will gain kinetic energy due to which there will occur collisions between them.
Also, 
Hence, more is the heat provided to the cake more will be the kinetic energy of its molecules due to which when we touch it, it feels hot.
Thus, we can conclude that molecules in the cake are moving faster than molecules in the skin, best explains why the cake feels hot.
Answer:
Explanation:
Air is a mixture of roughly 80% nitrogen and 20% oxygen. The diatomic molecules of each type have a Maxwell-Boltzman distribution of velocities.
From the kinetic theory of gases the molecules kinetic energy will depend on the temperature.
Let’s use 300 K as room temperature : The nitrogen molecules have a root mean square velocity ( VRMS ) of 353 m/s. The average for all of the molecules is 347 m/s.
In general in gases of diatomic molecules the speed of sound is 68% of the molecular VRMS .
Answer:
the rust formed because of the water sitting in sied a metal bowl for long time but they can fix this if they get filters
Explanation:
Answer: Yes
The antibonding orbital is empty. Thus, H2 is a stable molecule.
