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

Two identical containers with identical particle types and numbers are placed back to back and separated by a moveable barrier as shown in the animation (volume is in 10^-15m³, pressure is in 10^-9Pa, and temperature is in Kelvin).  Initially the barrier is in static equilibrium. If you doubled the number of particles in the right container, what would the temperature of the left container be in order to regain equal volumes? 

After a few seconds Set N Right and view the animation. The animation will run for about 15 seconds. Test your results by using Set T Left after you add particles to the right container. Start

A spherical air-filled balloon expands due to a temperature change as shown in the animation (position is in centimeters and time is in seconds). What is the ratio of the final to the initial pressure of the air in the balloon? Start

A spherical air bubble rises in a large pool of water as shown in the animation (position is in meters and time is in seconds). What is the ratio of the final to the initial temperature of the air in the balloon? Start

A spherical air bubble rises in a large pool of unknown liquid as shown in the animation (position is in meters and time is in seconds). What is the density of this fluid? Start
