Question

7 Which of these determines whether or not heat flows in a system?
average speed of the consituent particles of the system
pressure difference between parts of the system
degree of hotness or coolness of the system
temperature difference between parts of the system

8 Which of the following is NOT true about conduction as a means of heat transfer?
transfer of heat occurs through sucessive collisions of the atoms or molecules
the average kinetic energy of the atoms or molecules is greater in the hot object than in the cold object
the transfer process requires a material medium for it to take place
there is net translational motion of the atoms or molecules from their mean equilibrium positions

Answer 1

Question 7 Which of these determines whether or not heat flows in a system?

average speed of the consituent particles of the system

pressure difference between parts of the system

degree of hotness or coolness of the system

temperature difference between parts of the system

8 Which of the following is NOT true about conduction as a means of heat transfer?

transfer of heat occurs through successive collisions of the atoms or molecules

the average kinetic energy of the atoms or molecules is greater in the hot object than in the cold object

the transfer process requires a material medium for it to take place

there is net translational motion of the atoms or molecules from their mean equilibrium positions

Solution 7.Temperature difference between parts of the system determines whether or not heat flows in a system

8. there is net translational motion of the atoms or molecules from their mean equilibrium positions - this is NOT true about conduction as a means of heat transfer.
