What is the name of a phase change between a gas into a liquid?  a condensation  b evaporating  c melting  d freezing

The temperature on a sample of pure X held at 1.13 atm and -9. °C is increased until the sample boils. The temperature is then held constant and the pressure is decreased by 0.39 atm. On the phase diagram below draw a path that shows this set of changes. 200 400 temperature (K) pressure (atm)

Classify cach substance as an ionic solid, a molecular solid, a metallic solid, or a polymer. lonic Solid Molecular Solid Metallic Solid Polymer Answer Bank shovel blade shovel handle ice in glass ice melt garden hose

need help with this chemistry

At constant pressure p1, the substance goes from solid state to gas as temperature increases   At constant temperature T1, the substance goes from gas state to liquid as pressure increases   The substance exists in the liquid phase by lowering the pressure and the temperature beyond T   At temperature T, the substance coexists in solid, liquid and gas phases   At constant pressure p2, the substance goes from solid state to liquid to gas as temperature increases.
