Chemical Properties of Matter
The ability to catch on fire
What is flammability?
The mass of an object compared to its volume.
What is Density?
What is the 1st Law of Thermodynamics?
energy cannot be created or destroyed; it can only be converted from one form to another.
Define matter.
any substance that has mass and takes up space by having volume
The ability to be poisonous
What is toxicity?
Ability to be pounded into thin sheets
What is malleability?
What is thermal equilibrium?
when two objects in thermal contact no longer affect each other's temperature
What is solubility?
Ability to dissolve in another substance
The ability to react with oxygen
What is oxidation?
Ability to transfer thermal energy from one area to another
What is thermal conductivity?
What is the 2nd Law of Thermodynamics?
the state of entropy of the entire universe, as an isolated system, will always increase over time.
What is heat?
the transfer of thermal energy from one physical system to another system
What are signs of chemical changes in matter?
Ability to carry electricity
What is electrical conductivity?
What is the 3rd Law of Thermodynamics?
states that the entropy of a perfect crystal at a temperature of zero Kelvin (absolute zero) is equal to zero
What is temperature?
a measure of the average amount of energy of motion, or kinetic energy, a system contains.
What is the difference between chemical and physical properties?
Chemical properties are properties that can be observed or measured when a substance undergoes a chemical change. Physical properties are properties that can be observed without bringing a chemical change.
Ability to be drawn or pulled into a wire
What is ductility?
Calculate the heat required to raise the temperature of 200g of water from 25 ºC to 75 ºC.
C = 4.18 kJ/kg*ºC.
41.8 kJ
Define Entropy
measure of the disorder of a system
