Physical Properties and Intermolecular Forces | Chemistry
Physical Properties and Intermolecular Forces The physical state and properties of a particular compound depend in large part on the type of chemical bonding it displays. Molecular compounds , sometimes called covalent compounds, display a wide range of physical properties due to the different types of intermolecular attractions such as different kinds of polar interactions.
8(p) Physical and Chemical Characteristics of Seawater
Physical and Chemical Characteristics of Seawater. Seawater is a mixture of various salts and water. Most of the water in the ocean basins is believed to originate from the condensation of water found in the early atmosphere as the Earth cooled after its formation. This water was released from the lithosphere as the Earth''s crust solidified.
