For liquid water the isothermal compressibility is given by: κ = c V(P + b) where c and b are functions of temperature only. If 1 kg of water is compressed isothermally and reversibly from 1 to 500 bar at 60°C, how much work is required? At 60°C, b = 2700 bar and c = 0.125 cm3·g–1.

When did stem cell research become known ? who discovered stem cell? what experiments or studies have been conducted so far?

Asubstance is held in an open container. its particles move past one another at random speeds but do not leave the container. heat is removed from the system, and the particles slow down. when enough heat is removed, the particles no longer have enough speed to overcome the weak attractive forces between them. when this happens, the substance enters its solid state. the process described above is known as .

What is the density, d, of a substance with a volume of v = 12.5 cm3 and a mass of m = 74.4 g ?
