Problem 23P

You construct two wire-frame cubes, one using copper wire, the other using aluminum wire. At 23 °C the cubes enclose equal volumes of 0.016 m3. (a) If the temperature of the cubes is increased, which cube encloses the greater volume? (b) Find the difference in volume between the cubes when their temperature is 97 °C.

Solution 23P

Step 1 of 3

The volumetric expansion of an object can be described by using the equation,

Where - Coefficient of volumetric expansion

- Volume of the object

- Change in temperature of the object.
