These flashcards cover essential vocabulary and concepts from the CHEM17370 Introductory Chemistry I lecture notes, aiding in understanding key terms and their definitions.

Specific Heat Capacity

The amount of energy required to raise the temperature of a substance by one degree Celsius.

Calorimetry

A process for measuring the heat of chemical reactions or physical changes.

Internal Energy (∆E)

The total energy contained within a system.

Exothermic Reaction

A reaction that releases heat to its surroundings.

Endothermic Reaction

A reaction that absorbs heat from its surroundings.

Ionization Energy

The energy required to remove an electron from an atom in its gaseous state.

Electronegativity

A measure of the tendency of an atom to attract a bonding pair of electrons.

Ionic Bond

A chemical bond formed between two ions with opposite charges.

Covalent Bond

A chemical bond that involves the sharing of electron pairs between atoms.

Molar Volume at STP

The volume occupied by one mole of an ideal gas at standard temperature and pressure, approximately 22.42 L.

Hydrogen Bonds

A strong attractive force between a hydrogen atom bonded to an electronegative atom and another electronegative atom.

London Forces

Weak intermolecular forces arising from temporary dipoles in molecules.

Boiling Point

The temperature at which a liquid turns into vapor.

Melting Point

The temperature at which a solid becomes a liquid.

Chemical Equation

A symbolic representation of a chemical reaction in which the reactants and products are shown.

Enthalpy Change (∆H)

The heat content change of a system at constant pressure.
