Question

well what are state variables in thermodynamics

Answer 1

I'm wondering if you can help me with a practical application....I'm trying to determine when safety shoes are required for protection against the impact of a heavy item falling onto the foot. I used the calculator and learned that an 11kg object falling 1 m has a velocity of 4.43 m/s, kinetic energy before inpact 107.8 and the distance travelled after impact of 0.01m equals 10780 newtons. I'm having trouble understanding what a newton is and how many newtons will break a bone in the foot. I appreciate any help you can provide. Thank you very much.

Answer 2

The state variables in thermodynamics are a set of physical parameters that describe the energy of the system. These tend to come in complimentary pairs, such as Pressure and volume, entropy and temperature, stress and strain etc.,
