14.

Relating to specific heat; why does submerging a hot iron in water of equal mass drastically change the temperature of the iron while only changing the temperature of water by a much smaller amount?

water has a higher specific heat while iron has a low specific heat

both iron and water have low specific heat, so it shouldn't effect it differently

iron has a high specific heat while water has a low specific heat

both iron and water have high specific heat, so it shouldn't effect it differently

15.

What would be the effect on the particles if more heat is supplied to the system?

They would slow down

They would stop moving

They would speed up

There would be no effect

16.

0th law of thermodynamics

1st law of thermodynamics

2nd law of thermodynamics

3rd law of thermodynamics

17.

From lowest entropy to highest entropy, the states of matter go in this order:

solid -> liquid -> gas -> plasma

plasma -> gas -> liquid -> solid

gas -> plasma -> liquid -> solid

solid -> liquid -> plasma -> gas

It depends on the temperature of the object
