Thermodynamics

QuestionAnswer
Define Density the mass per unit volume
Define the density equation for the mass of atoms rho = Ma/(2Ra)^3
Define the mass of the atom in terms of the atomic weight and avocado's number Ma=AWg/Na
How are atoms seen By using shortwave radiation which is smaller than the diameter of the atom.
Define Kinetic Energy the energy that a moving body has Ek = (m/2)*v^2
Show the relationship between momentum and kinetic energy Ek = (p^2)/(2m)
Show the equation for thermal linear expansion. Delta(L)=Lo*Delta(T)*coefficient.
Explain how thermal expansion occurs The change in the temperature changes the energy state of the atoms making them take up more space and increasing the dimensions of the object.
Show the equation for thermal volume expansion. Delta(V)=Vo*Delat(T)*coefficient
Explain thermal equilibrium. This occur if and only if the systems have the same temperature.
Change Fahrenheit to Celsius. Tc=9/5(Tf-32)
Define the kelvin scale The kelvin scale start at -273.15 deg Celsius.
Show the constant-volume equation for temperature T2/T1=P2/P1 P=pressure

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
