How much times gases are more compressive compare to solids ?

How much time is required for complete decomposition of two moles of water at anode using 4 amperes current?

Explain with the basis of bulk modulus that solids are more compressive and gases are least compressive.

If a compressive force of 3.0xx10^(4)N is exerted on the end of a 20 cm long bone of cross-sectional area 3.6cm^(2) (i) will the bone break and (ii) if not by how much length does it shorten? Given compresive strength of bone =7.7xx10^(8)N//m^(2) and young's modulus of bone =1.5xx10^(10)N//m^(2)
