Energy
Which energy is the energy of movement
kinetic energy
When this is constant, kinetic energy increases
potential energy
How do you make a real gas act like an ideal gas
lower the pressure
An unknown gas has the original pressure and temperature of 3948 Pa and 200 K. If the temperature of the gas is raised to 300 K, what is the new pressure?
5922 Pa
Convert 10 C into K
283 K
What is another word for average kinetic energy
temperature
When this is constant, potential energy increases
kinetic energy OR temperature
what has no attractive forces?
I have an unknown volume of gas at a pressure of 0.5 atm and a temperature of 325 K. If I raise the pressure to 1.2 atm, decrease the temperature to 320 K, and measure the final volume to be 48 liters, what was the initial volume of the gas?
117 L
what process separates based on polarity?
