What is the average speed of the smallest molecular weight gas in the graph shown below? 0.004 0.003 Probability density (s/m) 0.002 0.001 0 500 1000 1500 2000 2 Speed (m/s) O 250 m/s 500 m/s 400 m/s 1100 m/s​

answer: i would say b.

explanation:

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.

the dependant variable is spilled water

the independent is the heat

answer : a model is often used to explain and make things easier to understand when any scientific topic needs to be demonstrated and explained.

as in this case where a scientist wants to use a model to present the results of his detailed scientific investigation. he should do it as it will him to make the audience understand the concept in a much better way. also, it can be changed according to new scientific understandings.
