Two spheres are made of the same metal and have the same radius, but one is hollow and the other is solid. The spheres are taken through the same temperature increase. Which sphere expands more? (a) solid sphere, (b) hollow sphere, (c) they expand by the same amount, or (d) not enough information to say.

Suppose you have two meter sticks, one made of steel and one made of invar (an alloy of iron and nickel), which are the same length (1.00 m) at 0°C. The coefficients of volume expansion for steel and invar are 3.6 × 10-5 /°C and 2.7 × 10-6 /°C respectively. apparently, you need to use the volume expansion formula below & have B=3a. have no idea how to turn the length into a volume for this problem. have no idea what value alpha is...

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.

Homework 2: Problem 7:   When builders were constructing a sidewalk they forgot to include an expansion joint between two of the segments, L = 1.7 m at To = 20° C. Assume the opposite ends of each segment are fixed and the linear expansion coefficient is α = 11.8 × 10-6 °C-1. Part (a)  As the day heats to Tb the segments press against each other and begin to raise the junction a distance h forming a triangle. What is the height (in meters) at Tb=110° F? h = ______ m Part (b)  What should the gap have been, in units of meters, to prevent them from touching? g = ______m

A steel beam 12 m sits next to a concrete wall when the temp is 20 degree A gap must be left between the beam and the concrete wall for expansion purposes. If the temp rises to 45 degrees C how large must the gap be if the steel beam just touches the concrete wall? Coefficient of linear expansion of steel 12X10-6 C-1.    I thought it was 1.20X10-3 but I was wronge  a. 3.60X10-3 b. 1.20X10-3 c. 2.40X10-3 d. 5.10X10-3
