A metal bar is is heated as shown in the animation (position is in centimeters and time is in seconds). What is the coefficient of expansion of the material? Start

Metal bars are heated as shown in the animation (position is in centimeters and time is in seconds). Are all of the metal bars made of the same material or not?

Two aluminum alloy bars (coefficient of thermal expansion of  25 x 10^-6 1/C^o) fit together snugly until subject to a change in temperature as shown in the animation (position is in meters and time is in days). Find that change in temperature. Start

A 2 kg hammer strikes a 1.5 gram iron  nail (c = 450 J/ kg ^. C^o) as shown in the animation (position given in centimeters and time is in seconds). Assuming that all of the energy is absorbed by the nail, estimate the temperature rise of the nail.   Start

A 1.5 kg brick falls a given height onto a 15 gram lead spike (c = 130 J/ kg ^. C^o) as shown in the animation (position is in meters and time is in seconds). Assuming that all of the energy is absorbed by the nail, estimate the temperature rise of the nail.   Start

A blue sportscar (m=2000 kg)  hits a brick wall (c = 450 J/ kg ^. C^o and M=4000 kg) as shown in the animation (position is in meters and time is in seconds). Determine the temperature change of the brick wall. Assume all of the energy lost goes into heating the wall.  Start
