Thermal Expansion

A meter long rod of unknown material is being heated by steam.

The change in radius of the bar by measuring angular velocity.

Calculations for energy lost in fusion, heating, and boiling.

The calculations showing that the coefficient of thermal expansion is similar to that of steel.

The steps and specific values and calculations for transfer of heat lab

The experimental set up

The graph of heat vs time. Showing specifically time when ice was present and when the temperature leveled off at the boiling point.

Uncertainty for the Latent Heat of Fusion (J/g)

Uncertainty for the Latent Heat of vaporization (J/g)

the uncertainty for the specific heat of water

The percent deviation from the accepted values. The Latent Heat of Fusion is off by 20% because of the inability to take into account the energy spent in the water or the rate of change from the ice into the water. The Latent Heat of Vaporization is off because the Logger Pro stopped recording before the heat was finished transferring throughout the water.

A video showing that heat is causing the ring to expand, so that the cool ball can fit through.

Heat causes brass to expand faster than the substance opposite it when heat is applied directly to the brass.

The brass still expands faster even when the heat is applied to the substance opposite it.
