How does thermal energy transfer when a room is heated by a furnace?
Anna007 [38]
The answer is B,This is an example of convection, where fluid will circulate.This is because when part of air is warmed up, they expand and become less dense then rise,Therefore, the colder air contracts and become denser and sinks, in order to take in the place of the warm air. This phrase circulates and therefore the it can transfer heat a lot more faster.

= 16.042g/mol

7.31 x 10^25 molecules x             1 mole  CH4      = 121.43 moles

                                      6.02 x 10^23 CH4 molecules

121.43 moles CH4 are present.
