The default temperature unit for this course is Kelvin0 K = 273.15C Temperature is a measurement of the average kinetic energy. K E = %kT for each translational degree of freedoms. k is the Boltzmann constant. Recall that kinetic energy is %mvz where m is the mass of a molecule and v is the velocity of that molecule. k=138 x 1072 J/K There are 3 translational degrees of freedom for any atom or molecule in 3.D space. Our universe has 3 dimensions for space. During collisions, momentum transfer among the colliding parties and they exert forces on each other. We will treat all collisions as perfectly elastic collisions (no change in kinetic energies). Pressure is the amount of force per unit area: P = % , A is area and Fis the total amount of force on that area.

Answer in units of Joules Type your answer... ........ 1 point & = Some molecules are initially at temperature T" and have the average velocity of v. When the temperature is doubled, how much is the velocity scaled by? For example, if the velocity becomes 10 times bigger, answer 10. Keep 3 decimal places. ........ n 1 point & |.>E Some molecules are initially at temperature 7" and have the average velocity of v. When the temperature is tripled, how much is the velocity scaled by? For example, if the velocity becomes 10 times bigger, answer 10. Keep 3 decimal places. Type your answer... 8 1 point With n, V, T being constant, when the pressure is 3 time larger, how much does the temperature scale by? Type your
