phy sci ch. 14 temp

temp lesson

QuestionAnswer
temp measureof how hot( or cold) something is; specifically a measure of the averagekinetic energy of the particles in sn object
thermometer instrument that measures and indicates temp
absolute zero the temp at which molecular energyis at a minimum(0 K on the Kelvin scale or -273.15 C on the Celsius scale)
heat energy transferred between objects that are at diff. temps
thermal conduction transfer of energy a heat througha material
convection movement of matter due to diff. in densitythat are caused by temp. variations( aircurrents)
convection current movement of matter that results from diff. in density; may be vertical, circular, or cyclical.
radiation energy that is transferred as electromagnetic waves, such as visible light and infrarred waves
specific heat quanity of heat required to raise a unit mass of homogenous material 1K or 1C in a specified way given constant pressure or vo;ume
entropy measure of the randomness or disordere of a system
heat engine machine that transforms heat into mechanicial energy or work
what is the formula from celsius to farheniet? Tc x 1.8 + 32
what is the formula for farheinet to celsius? Tf- 32 / 1.8
what is the formula for celsius to kelvin? Tc +273
whta is the formula for kelvin to celsius? Tk-273
what is the original specific heat formula? e=cm^t
WHAT IS THE EQUATION WHEN YOU ARE TRYING TO FIND SPECIFIC HEAT? c=e / m x ^t
1st law of therodynamics the transfer of energy neither creates nor destroys it.
2nd law of therodynamics energy transferred as heat always moved from objects w/ a higher temp. to objects w/ a lower temp.
whats the unit for energy? joules
whats the unit for specific heat? j/kg x K
what is the unit for temp? C or K
whats the unit for mass? kg

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.
