chapter 8: temperature & ideal gas 🌡

Question 1

definition of thermal equilibrium

Answer 1

no net exchange of energy when two objects are placed in thermal contact

Question 2

when will there be no net transfer of thermal energy between two objects

Answer 2

when they have same temperature

Question 3

does the rate of thermal energy transfer depend on the difference in temperature between the two objects?

Answer 3

yes. larger the difference in temperature, higher rate of energy transfer

Question 4

definition of ideal gas

Answer 4

is a gas that will obey the ideal gas equation, pV=nRT for all thermodynamic temperature, T, volume, V and pressure p when it is a fixed mass of gas

Question 5

what are the assumptions of the kinetic theory of gases?

Answer 5

1. any gas is made up of a large number of particles
2. the particles are in constant and random motion
3. the particles make perfectly elastic collisions among themselves and with the wall of the container
4. volume of each particle is negligible compared to the volume of gas
