own write-up. Problem 1: At 20°C, a rod is exactly 20.05 cm long on a steel ruler. Both are placed in an oven at 270°C, where the rod now measures 20.11 cm on the same ruler. What is the coefficient of linear expansion for the material of which the rod is made? The coefficient of expansion for steel is as = 11 × 10-6/°C.

You pour 998.00 cm3 of liquid mercury into a 1000.00 cm3-flask when both the mercury and the glass are at 4.0 ◦C. Determine the maximum temperature you can heat the system to (to the thousandth of a degree Celsius) before the mercury overflows. The mercury has a coefficient of volume expansion of 18.0 × 10−5◦C^−1 and the glass of the flask has a coefficient of volume expansion of 1.8 × 10−5◦C^ −1.

The active element of a certain laser is made of a glass rod 31.0 cm long and 1.60 cm in diameter. Assume the average coefficient of linear expansion of the glass is equal to 9.00 x 10° (°C). The temperature of the rod increases by 64.0°C. (a) What is the increase in its length? cm (b) What is the increase in its diameter? cm (c) What is the increase in its volume? cm

The gap width is 1.610 cm when the temperature is 30.0°C. Determine the gap width when the temperature is 205°C. (Use 11 ✕ 10−6 (°C)−1 for the average coefficient of linear expansion for steel. Give your answer to at least three decimal places.)

A hollow aluminum cylinder 19.5 om deep has an internal capacity of 2.000 L at 21.0°C. It is completely filled with turpentine at 21.0°C. The turpentine and the aluminum cylinder are the slowly warmed together to 79.0°C. (The average linear expansion coefficient for aluminum is 24 x 10-c, and the average volume expansion coefficient for turpentine is 9.0 103) (a) How much turpentine overflows? cm³ (b) What is the volume of turpentine remaining in the cylinder at 79 0°C? (Give your answer to at least four significant figures) (c) If the combination with this amount of turpentine is then cooled back to 21.0°C, how far below the cylinder's rim does the turpentine's surface recede? om

Thank u! A steel rule is calibrated for measuring lengths at 20.00°C. The rule is used to measure the length of a Vycor glass brick: when both are at 20.00°C, the brick is found to be 30.90 cm long. If the rule and the brick are both at 85.00°C, what would be the length of the brick as measured by the rule? Coefficient of linear expansion a for steel is 12.0 x10^-6 K-1 and for glass (Vycor) is 0.750 x 10^-6 K^-1.
