What is the formula to determine the work done in heating or cooling unit volume of a substance?

I understand that the term "work" is used mainly for the transfer of mechanical energy. So, perhaps, the more appropriate term here would be "energy".

You would have to find the material's thermal inertia, in this case, its volumetric heat capacity - look it up, usually, or calculate it on the basis of its specific heat, which you would look up instead. Once you have that, just multiply the volume x the desired difference in temperature.

What happened to the Hindenberg airship?

On 6 May 1937, the Hindenburg was approaching a mooring mast at Lakehurst Naval Air Station in New Jersey when it caught fire. The flames first appeared near the tail and, within 37 seconds, completely engulfed the ship. Of the 97 people on board, 35 were killed, as well as one of the ground crew.

Various theories have been put forward regarding the cause of the blaze. Investigators ruled out sabotage. More likely theories suggest that the fire was started by a spark caused by static buildup, or that one of the many high-tension bracing wires within the structure of the airship may have snapped and punctured the fabric of one or more of the internal gas cells.
