- Two concrete spans that form a bridge of length L are placed end to end so that no room is allowed for expansion (Fig. P16.63a). If a temperature increase of T occurs, what is the height y to which the spans rise when they buckle (Fig. P16.63b)?arrow_forwardAn aluminum rod 0.500 m in length and with a cross-sectional area of 2.50 cm2 is inserted into a thermally insulated vessel containing liquid helium at 4.20 K. The rod is initially at 300 K. (a) If one-half of the rod is inserted into the helium, how many liters of helium boil off by the time the inserted half cools to 4.20 K? Assume the upper half does not yet cool. (b) If the circular surface of the upper end of the rod is maintained at 300 K, what is the approximate boil-off rate of liquid helium in liters per second after the lower half has reached 4.20 K? (Aluminum has thermal conductivity of 3 100 W/m K at 4.20 K; ignore its temperature variation. The density of liquid helium is 125 kg/m3.)arrow_forwardIf the gas in Exercise 23 is initially at room temperature (20C) and is heated in an isobaric (constant-pressure) process, then what will be the temperature of the gas in degrees Celsius when it has expanded to a volume of 0.700 m3?arrow_forward
- At 25.0 m below the surface of the sea, where the temperature is 5.00C, a diver exhales an air bubble having a volume of 1.00 cm3. If the surface temperature of the sea is 20.0C, what is the volume of the bubble just before it breaks the surface?arrow_forwardAn aluminum rod 0.500 m in length and with a cross sectional area of 2.50 cm2 is inserted into a thermally insulated vessel containing liquid helium at 4.20 K. The rod is initially at 3(H) K. (a) If one-halt of the rod is inserted into the helium, how many liters of helium boil off by the time the inserted half cools to 4.20 K? Assume the upper half does not yet cool, (b) If the circular surface of the upper end of the rod is maintained at 300 K. what is the approximate boil-off rate of liquid helium in liters per second after the lower half has reached 4.20 K? (Aluminum has thermal conductivity of 3 100 YV/m K at 4.20 K; ignore its temperature variation. The density of liquid helium is 125 kg/m3.)arrow_forwardOne way to cool a gas is to let it expand. When a certain gas under a pressure of 5.00 106 Ha at 25.0C is allowed to expand to 3.00 times its original volume, its final pressure is 1.07 106 Pa. (a) What is the initial temperature of the gas in Kelvin? (b) What is the final temperature of the system? (See Section 10.4.)arrow_forward
- Star A has twice the radius and twice the absolute surface temperature of star B. The emissivity of both stars can be assumed to be 1. What is the ratio of the power output of star A to that of star B?

What will its height be on a day when the temperature falls to -10.0 ? Although the monument is made of limestone, assume that its coefficient of thermal expansion is the same as that of marble. Give your answer to five significant figures.arrow_forward
- Your answer is partially correct. An aluminum cup of 76 cm capacity is completely filled with glycerin at 19°C. How much glycerin will spill out of the cup if the temperature of both the cup and glycerin is increased to 31°C? (The linear expansion coefficient of aluminum is 23 x 10-6 1/C°. The coefficient of volume expansion of glycerin is 5.1x 10-4 1/C°) Number i 0.0766 Units cm^3arrow_forwardA thermometer has a mercury-filled glass bulb with a volume of 2 x 10-7 m3 attached to a thin glass capillary tube with an inner radius of 5 x 10-5 m. If the temperature increases by 100°C, how far will the mercury rise in the tube? (volume thermal expansion coefficient of mercury= 1.82 x 10-4 K-1).arrow_forwardA sidewalk is made in squares of length 1 meter on each side, with expansion gaps between segments to avoid cracking. If sidewalk concrete has a linear expansion coefficient of 15*10^-6 (1/K), how far apart do the expansion gaps need to be to ensure that the sidewalk doesn't crack? Assume a 50 K temperature variation of the sidewalk.arrow_forward
