Question №º3.3. (Problem 3.9 from Finn's Thermal Physics) Your 200-g cup of coffee is toohot to drink at 95°C. Assume coffee has the same thermal properties as water.(a) Suppose you want to cool the coffee by adding 20°C water. How much water do youneed to add so that the mixture reaches equilibrium at 75°C?(b) Instread of water you use ice initially at 0°C to cool the coffee. How much ice is neededto bring the mixture to equilibrium at 75°C?

Given data : mc = 200 gm Tc = 95°C Tw = 20°C Ti = 0°C To find : mw and mi

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…
