Founder of hydrotherapy in USA 1901 in which his theory is "Rational Hydrotherapy "
John Harvey Kellogg
Scientifically it is a chemical compound made of two types of atom: one atom of oxygen and two of hydrogen = H20.
What are the characteristics of water?
Known as universal solvent .
Dissolves almost everything –except oil
Can be solid, a liquid, a vapour
Can be floated on, traveled under
used as counter weight Creates electrical energy
What is the Percentage of water in the human body?
adult male is 60%
adult female is 55%
baby is 73 to 80%
elderly are 45%
What is the percentage of water in the muscles?
What is the percentage of water in the bones?
What is the percentage of water in the Blood?
Percentage of water: The brain _____ is water and brain cells ______ are water.
What is the boiling point of water?
100 degrees Celsius
What is the freezing point of water?
0 degrees Celsius
True or False:
Measures and Actions of Water:
H2O = 1ml = 1cc= 1gr
Specific gravity (measured using water) = 1 gram/cubic centimetre
Specific heat- one calorie is required to raise one gram of water, one degree Celsius
___________ - is the thermal energy required or liberated by water, in order for it to change its state from liquid, to solid to gas.
What is the maximum temperature of water?
100 degrees Celsius
To heat one gram of water from 0 degrees Celsius to 100 degrees Celsius, What is the calorie of thermal energy is required?
Over 100 degrees Celsius, the speed of molecular movement is ___________ , until the bond holding the molecules together is overcome and water changes to gas (vapour).
How many calories of heat is liberated when water cooled from 100 degrees Celsius to 0 degrees Celsius?
100 calories of heat
540 calories of heat is required to vaporize one gram of water this is known as:
latent heat of vaporization
540 calories of heat must be released to re-establish the liquid state, this is known as:
latent heat of condensation
To convert 1 gram of water from 0 degrees Celsius to ice, a further 80 calories must be liberated; this is called:
latent heat of fusion
Conversely 80 calories of thermal energy are required, to free the molecular bond producing 1 gram of water at 0 degrees Celsius. This is known as:
latent heat of melting
