Chapter 3.1

Question 1

What is the zeroth law of thermodynamics

Answer 1

• when one object is in thermal equilibrium with another
• > then that object will also create thermal equilibrium when another object touches it
• thermal equilibrium=no net heat will flow between objects

-eg; if a=b and b=c, then a=c

Question 2

What is temperature defined as on the molecular level

Answer 2

-the average kinetic energy of particles that make up a substance

Question 3

What does heat refer to

Answer 3

• the transfer of thermal energy

- >from an object with a higher temperature to that of a lower temperature

Question 4

What is absolute zero defined as

Answer 4

• the theoretical temperature
• > at which there is no thermal energy
• the freezing point of water is 273.15 K

Question 5

What does the third law of thermodynamics state

Answer 5

-entropy of a perfectly organized crystal at absolute zero is zero

Question 6

How do you convert celcius to farenheit and kelvin

Answer 6

F= 9/5(C) +32
K= C+273
