. After sitting outside on a cold night, the pressure in the tires of your car is 26 psi. If you drive your vehicle to work, a distance of 2h miles, at highway speeds, would you expect the tire pressure to increase, decrease, or remain the same? Explain the rationale for your choice. Assume that me outside air temperature remains constant during your trip.

Problem 1.1. The Fahrenheit temperature scale is defined so that ice melts at
32°F and water boils at 212°F.
(a) Derive the formulas for converting from Fahrenheit to Celsius and back.
(b) What is absolute zero on the Fahrenheit scale?
Problem 1.2. The Rankine temperature scale (abbreviated °R) uses the same
size degrees as Fahrenheit, but measured up from absolute zero like kelvin (so
Rankine is to Fahrenheit as kelvin is to Celsius). Find the conversion formula
between Rankine and Fahrenheit, and also between Rankine and kelvin. What is
room temperature on the Rankine scale?
1.1. In the table below, a number in the top row represents the pressure of a gas in the
bulb of a constant-volume gas thermometer (corrected for dead space, thermal
expansion of bulb, etc.) when the bulb is immersed in a water triple-point cell. The
bottom row represents the corresponding readings of pressure when the bulb is
surrounded by a material at a constant unknown temperature. Calculate the ideal-
gas temperature T of this material. (Use five significant figures.)

(a) Derive an equation for dL/dt in terms of L , the temperature T above the ice, and the propertiesof ice (which you can leave in symbolic form instead of substituting the numbers). (b) Solve this differential equation assuming that at t = 0 , you have L = 0. If you have studied differential equations, you will know atechnique for solving equations of this type: manipulate the equation to get dL/dt multiplied by a (very simple) function of L on one side, and integrate both sides with respect to time.
