4. An aluminum baseball bat, which is 0.8950 m in length when the temperature is 34.7°C, is left outside over night. If the temperature that night reaches freezing, what would be the bat's new length? Coefficient of linear expansion standard value

Suppose a gas-filled incandescent light bulb is manufactured so that the gas inside the bulb is at atmospheric pressure when the bulb has a temperature of 20.0°C. a.  Find the gauge pressure, in standard atmospheres, inside such a bulb when it is hot, assuming its average temperature is 59.5ºC and neglecting any change in volume due to thermal expansion.  b. The actual final pressure for the light bulb will be less than calculated in part (a) because the glass bulb will expand a small amount. What will the actual final gauge pressure be, in standard atmospheres, assuming the thermal coefficient of volume expansion is 2.7 × 10-5/°C?

Suppose a 22.5°C car tire contains 3.85 mol of gas in a 32.5 L volume. What is the gauge pressure, in atmospheres, in the car tire? Pg1 = What will the gauge pressure be if you add a quantity of gas that had a volume of 2.00 L when it was at atmospheric pressure and the same temperature as the tire? Pg.2

3. You are standing in a (cold) room and the temperature at a point in the room is given by the equation T(x, y) = 0.005x² + 0.01y², where r and y are measured in inches from a central point in the room and T is measured in degrees Fahrenheit. You are standing at a point with coordinates (60, 40). The positive r-axis points due east and the positive y-axis points due north. (a) If you walk due west, will the temperature increase or decrease? (b) In which direction is the temperature change greatest? (c) What is the rate of temperature change in that direction?
