A Fahrenheit and a Celsius thermometer are both immersed in a fluid. a) If the two numerical readings
are identical, what is the temperature of the fluid expressed in °K and °R. b) If the Fahrenheit
temperature is numerically twice that of the Celsius reading, what is the temperature of the fluid
expressed in °K and °R?
H.W:
A mass flow rate m(g/s) is measured as a function of temperature T(°C).
T
10
20
40
80
m 14.76 20.14 27.73 38.47
There is reason to believe that m varies linearly with the square root of T:
m = aT/2 + b
Use a straight-line plot to verify this formula and determine a and b.
A container filled with an ideal gas is connected to a reservoir of the same gas so that the number of moles in the container can change. If the pressure and volume of the container are each doubled while the temperature is held constant, what is the ratio of the final to the initial number of moles in the container?

Each molecule colliding with this portion of the wall exerts the following pressure on it: - m Δυ, ΑΔt where v, is the molecule's speed in the direction perpendicular to the wall. We assume an elastic collision, so over the course of the collision we have Avx = -2vx. An interesting quantity is N, the number of molecules colliding with this portion of the wall in (very short) time interval At. We can estimate that the gas pressure P, which is the total pressure exerted by N molecular collisions with the wall, is N times the average pressure exerted by a single molecule: 2Nm P = N…arrow_forward
