Exothermic chemical change

Front

- surroundings get warmer - temperature increases - reactants-->products + heat - making new bonds

Back

Exothermic Physical Change

Front

G-L-S G-S -temperature decreases

Back

Heat

Front

thermal energy transferred between two systems at different temperatures that come in contact

Back

System

Front

the reign being studied that is absorbing or releasing energy

Back

Endothermic Physical Change

Front

S-L-G S-G -temperature increases

Back

Endothermic

Front

a process in which a system absorbs heat from the surroundings from the environment

Back

Exothermic

Front

a process in which a system releases heat to the surrounding

Back

Endothermic chemical change

Front

- surroundings get cooler - temperature decreases - heat + reactants-->products - breaking bonds

Back

endothermic examples

Front

melting, vaporization, sublimation

Back

Exothermic examples

Front

freezing, condensation, deposition

Back

Surroundings

Front

the area external to the system

Back

Specific heat formula

Front

Q = m.c.ΔT

Back

Heat of vaporization

Front

the amount of heat absorbed as a specific quantity of a liquid becomes a gas

Back

Specific heat capacity

Front

the quantity of heat required to raise a unit of mass by 1k given constant temperature and pressure

Back

Molar heat capacity

Front

the quantity of heat required to raise one mole of a substance by 1k under constant temperature and pressure

Back

Heating curve

Front

A plot of the temperature versus time

Back

Heat of fusion

Front

the amount of heat absorbed as a specific quantity of a solid melts to a liquid

Back

Physical change

Front

a change that affect the shape of phases of a substance but does not produce a new substance
