Question 4 of 19

1

What is conduction?

Select one of the following:

  • Energy transferred by 2 things TOUCHING

  • Energy transferred through the movement of liquid or through CURRENTS

Question 6 of 19

1

What is convection?

Select one of the following:

  • Energy transferred from an energy source and DOESN'T have to travel through MATTER

Explanation

Question 7 of 19

1

What is thermodynamics?

Select one of the following:

  • The study of heat and thermal energy

  • The study of conversions between heat and other forms of energy

  • The study of particle movement

Explanation

Question 8 of 19

1

What is the 1st law of thermodynamics?

Select one of the following:

  • We can never reach absolute zero

  • Energy con never be created or destroyed and therefore must be conserved

  • Energy flows from hot → cold (to go from cold → hot, you must do work)

Explanation

Question 9 of 19

1

What is the 2nd law of thermodynamics?

Select one of the following:

  • Energy flows from hot → cold (to go from cold → hot, you must do work)

  • Energy con never be created or destroyed and therefore must be conserved

  • We can never reach absolute zero

Explanation

Question 10 of 19

1

What is the 3rd law of thermodynamics?

Select one of the following:

  • Energy flows from hot → cold (to go from cold → hot, you must do work)

  • We can never reach absolute zero

  • Energy con never be created or destroyed and therefore must be conserved

Explanation
