physical Property's
Definition of Physical Propertys
A physical property is a characteristic of a substance that can be observed or measured without changing the identity of the substance
What is Density
the degree of compactness or Concentration of a substance.
what is heat energy
Heat energy is a form of energy that results from the movement of atoms and molecules within a substance.
What gas do Human Exhale
CO2
Types of Physical Property's
Density
Electrical conductivity
Solubility
Melting point
Boiling point
Color
State of Matter
What is the Formula for density
D = M/V x A
What is the Equation for Heat energy
q = mcΔT
What do Humans Inhale
Oxygen
What are the physical properties of your water
Clear, Boils at 100 Celsius, Freezes at 0 Celsius, 1 g/cm3
Why does Ice float on water?
Because Ice Has less density than Liquid water causing it too float on the surface of water.
What is a better conductor of Heat Wood or metal
Metal
What Process to Plants undergo to create energy for themselves
Photosynthesis
what are the physicals property's of Steel
Hard, Metallic, Magnetic, Melts at 1370 Celsius
What is the Unit of Density?
g/cm^3
Why does metal feel colder to the touch than wood, even if they are the same temp?
Metal feels colder because it is a better heat conductor, meaning it can transfer heat to your hand faster than wood.
What is the Molar mass of hydrodgen?

If a block of wood has a mass of 50 g and a volume of 100 CM^3 what is the density?
0.5 g/cm^3
What unit is heat energy measured in
Joules (J)
What is the Molar mass of O2
