Question

Thermodyanmics Examples..

I need examples .. real life examples.. don't just say heat engines.. I mean.. when i teach processes like isothermal, adiabatic.. and stuff.. i mean.. where do we see this in action.. well i know the compressions in air when sound travels are adiabatic in nature.. which newton thought to be isothermal.. but the example is not good enough to keep them interested :(

Answer 1

them = students :D ..

Answer 2

any recommendations.. ??
well.. specific heat and thermal capacity when i talk about .. i can give loads of examples.. liek why during hot season, the land gets heated up but the water doesn't.. so they understand the true meaning of specific heat.. they understand the meaning of "specific heat of water is HIGH ".. they get it ..

Even thermal conductivity.. m able to make them understand, go beyond definition.. giving example of why certain materials (metals or something).. you know they feel cooler when held in hand.. compared ot plastic or something.. where in reality they are the same temperature.... so i need such examples.. and any recommendations... for ohter things we learn in thermodynamics!!

Answer 3

isothermal process is like to do work very slowly like if you press syringe very very slowly than it van exchange heat with surroundings this is isothermal process. And if you do it very fast than it cant exchange heat with surroundings than this is adiabatic process. We can also make the process adiabatic by making the walls diathermic but these will not exactly isothermal or adiabatic in real life but likely to be.

Answer 4

An ordinary steam engine has both isothermal and adiabatic processes at least sufficiently close to the ideal to be assumed in its operation.

Answer 5

newton it Boyle's law heated bath
