Chemistry homework


FINISH ANSWERING THESE


CHEMISTRY NOTES

1.     DEFINE

TEMPERATURE: the measurement of the amount of energy in something
·      If we lessen the kinetic energy (you cool it down)
·      If you add energy (the temperature will rise)

PRESSURE
·      Force applied per unit area

BAROMETER
·      Used to measure air pressure (Atmospheric Pressure)

MANOMETER
·      Measures a gas in a fixed container (volume)

PASCAL

ATMOSPHERE

DALTONS LAW OF PARTIAL PRESSURE

The two largest influences on gases are temperature and pressure.


2.     What two factors determine the kinetic energy of a particle? TEMPERATURE AND PRESSURE
How do we calculate the kinetic energy in a particle?


3.     What is the SI unit for temperature?

4.     What is the average air pressure at sea level?
What is the SI unit for pressure?
What is it equal to?
What is one atmosphere equal to in the following units: mmHg, torr, Kpa, psi, bar, inHg

STANDARD PRESSURE: They are all equal to each other, to one atmosphere
o   29.92 inHg
o   1 atm (Atmosphere)
o   101.3 KPa (used mostly in European region)
o   101300 Pa*
