How are membranes adjusted for different temperatures? A membrane remains fluid as temperature decreases, until finally the phospholipids settle into a closely packed arrangement and the membrane solidifies. The membrane remains fluid to a lower temp

4. (a) Let the reading on the Celsius scale be x and the reading on the Fahrenheit scale be y. Then y 9 x 32 . If we require y = 2x, then we have 5 2x which yields y = 2x = 320F. (b) In this case, we require y 9 x 32 5 x (5) (32) 160 C 1 2 x and

SOLUTION HOMEWORK 13 1. 59. In the following CV 3 2 R is the molar specific heat at constant volume, C p 5 2 R is the molar specific heat at constant pressure, T is the temperature change, and n is the number of moles. The process 1 2 takes pla

Chapter 4 1. (a) The magnitude of r is 5.02 + ( 3.0) 2 + 2.02 = 6.2 m. (b) A sketch is shown. The coordinate values are in meters. 2. Wherever the length unit is not specified (in this solution), the unit meter should be understood. ^ (a) The po

13. The wave speed v is given by v = , where is the tension in the rope and is the linear mass density of the rope. The linear mass density is the mass per unit length of rope: = m/L = (0.00 kg)/(2.00 m) = 0.0300 kg/m. Thus v 500 N 129 m s. 0
