Chapter 1 Flashcards
What are the 5 fundamental dimensions
- Length
- Mass
- Time
- Temperature
- Electric current
What is Length (L)
Measure of distance
What is mass (M)
Amount of matter in a body
What is time (T)
The interval between happenings
What is temperature
Measure of how hot or cold
What is electric current
Measure of electron flow
What are the fundamental dimensions of Force
ML/ T^2
What are the fundamental dimensions of acceleration
L / T^2
What are the fundamental dimensions of Energy
since E = force x distance
= M L ^2 / T^2
What are the fundamental dimensions of power
Since P = energy/ time
= ML^2 / T^3
What are the fundamental dimensions of Pressure
Since pressure = Force / area^2
= (M L/ T^2) / L^2
What is the cgs system
Centimetre, gram, second system
What is derived unit of volume in cgs
cc ( cubic centimeter )
What is derived unit of force in cgs
dyne
What is derived unit of Energy
erg
1 joule = ? erg
10^7 erg
1 calorie = ? erg
4.18 x 10^7 erg
What is the mks system
metre, kilogram, second system
What is the fps system
foot - pound-second system
1 mol = ? molecules
6.023 x 10^23 - avogadro number
What is avogadro number equal to
the number of atoms in 12g of carbon
unit for molar mass
g/mol or kg/kmol
moles equation
Mass (g ) / Molar mass (g/mol)
what should all the mol fractions of a component add up to
