Indigenous people sometimes cook in watertight baskets by placing hot rocks into water to bring it to a boil. What mass of 500.0C rock must be placed in 4.00 kg of 15.0C water to bring its temperature to 100.0C, if 0.0250 kg of water escapes as vapor from the initial sizzle? You may neglect the effects of the surroundings and take the average specific heat of the rocks to be that of granite.
In this example we see how thermal expansion can actually throw off the accuracy of a length-measuring device-namely, a tape measure. A surveyor uses a steel measuring tape that is exactly 50.000 m long at a temperature of 20 °C. What is its length on a hot summer day when the temperature is 35 °C? SOLUTION SET UP AND SOLVE We have Lo = 50.000 m. To (Note that because AL is usually much smaller than Lo, we need steel is 1.2 x 10-5 K-¹. Using the same equation, The new length is Part A - Practice Problem: 20 °C, and T 35 °C. We use the following equation to find AL: AL=aLo AT IVD ΑΣΦ Submit L = Lo + AL 50.000 m -0.0090 m : 50,009 m REFLECT The measuring tape lengthens by 9 mm, or 0.018%. In surveying a baseball field, this amount is negligible, but not when measuring the length of a steel bridge. Note that, although Lo is given to five significant figures, we need only two of them to compute AL. Request Answer keep more significant figures in the lengths than in the temperatures.) The…
