Density and Specific Heat Notes / Lesson

Density

• What is density?

• Add the information from the video to your notes

• Then answer the questions

Multiple Choice

How is density measured?

• mass / volume

• volume / mass

• volume x mass

• mass x volum

Multiple Select

What color is the most dense?

• red

• yellow

• blue

• orange

Multiple Select

Approximately What is the density of water?

• 1 g/cm3

• 4.184 g/cm3

• 0.5 g/cm3

• 124 g/cm3

Density of liquid water is 1 but.....

Depends upon temperature and air pressure, the colder the water the less dense it is until it freezes . . . the hotter the water the less dense it is until it evaporates

Need to see some examples done using density

• a couple examples worked through

• Write down some appropriate notes

You should

have completed your density notes

and completed your density worksheet from class

send both to your teacher over e mail

Specific Heat

• What is specific heat?

• Take notes on the video

Multiple Choice

What is the formula for specific heat?

• 
  

  $q\ =m\ c\ \Delta T$

• $m\ =\ q\ c\ \Delta T$

• $\Delta T\ =\ m\ c\ q$

• $c\ =\ m\ q\ \Delta T$

Multiple Choice

The higher the specific heat the

• more energy needed to raise the temp

• less energy needed to raise the temp

• it doesn't matter

How to use the specific heat formula

take the appropriate notes

write down some example please

then try the examples in the following slide

What you should have done

• finished your notes on Specific Heat

• Finished your Specific Heat WS from class

• E mail both to your teacher
