The general properties of matter such as color, density, hardness, are examples of physical properties. Properties that describe how a substance changes into a completely different substance are called chemical properties. Flammability and corrosion/oxidation resistance are examples of chemical properties. It also depends on what your doing to the soap Examples: iron and oxygen combining to make rust. vinegar and baking soda combining to make sodium acetate, carbon dioxide and water. things burning or exploding. Would be chemical reactions Examples of physical changes include crushing a can, melting an ice cube, and breaking a bottle.
From Boyle's law the volume of a fixed mass of a gas is inversely proportional to the pressure at a constant absolute temperature. Thus; K = PV Hence; P1V1 =P2V2 0.5 × 24 = 4× P2 P2 = 12/4 = 3 atm Therefore; the pressure will go from 24 atm to 3 atm
