Hot stuff

Heat .... ??

Heat is not temperature.

Often the concepts of heat and temperature are thought to be the same, but they are not.

Perhaps the reason the two are usually and incorrectly thought to be the same is because as human beings on Earth our everyday experience leads us to notice that when you add heat to something, say like putting a pot of water on the stove, then the temperature of that something goes up. More heat, more temperature - they must be the same, right? Turns out, though, this is not true.

Kinetic energy???

Question: In detail, what is the difference between kinetic energy
and thermal energy?

Kinetic energy is a general term describing the energy
associated with the motion of objects (large or small objects).
You can calculate the kinetic energy of an object of
mass m
with a velocity (speed) v from the formula

K.E. = 1/2 mv^2.

Thermal energy refers to the kinetic energy of the
microscopic particles (atoms and molecules) that
make up all samples of matter
- i.e. all objects.

When you add heat to an object, you increase
the temperature of the object (usually) and that
heat increases
the kinetic energy of the molecules
that comprise that object.

In fact, temperature is a measure of the average
kinetic energy
of the microscopic particles that
make up an object.

exothermic ? Endothermic?

How does Heat Transfer?


  1. So that would make kinetic energy and thermal energy different? Right?! Based on what I understand that is posted on the blog. I think?!

  2. HI Mr. V
    I have ben watching the news about the quake and tsunami in japan. Horrible thing but i hear we are rushing to help with a neuclear power plant. The coolants stoped working and they are releasing neuclear ions into the air to release some of the building pressure. Untill we can send mechanics to help this might go on. I serched this situation but could not find much, I was wondering what effects this may have on ... well everything. If it could effeect water, air, and if people come into contact if it will have negative effects or if you will get superpowers if you breathe it!

  3. Mr. V the Temperture vs Heat video really helped explain the differences. The exothermic and endothermic stuff really confused me. Whats a kilojolt? The formulas and stuff got me realy confused can you explain exothermic and endothermicn in a different way?

  4. Hey mr. v...again!
    Well its a day after i asked my question about the neuclear plants in japan and things have gotten worse. Now a total of 6 plants are having functioning problems. This raises a question, should there really be this many power plants(of this sort) on a ISLAND? Whatever the reason for them a neuclear melt down (as stated by the Japaneese government) is not likely to happen but will one plants ions effect another ones chance of blowing? Crazy stuff but if there is a neuclear melt down 1. will it grow untill nothing and 2. if there is a meltdown of smaller scale could it trigger more from other plants?

  5. We will cover a lot of this in class... you won;t get any superpowers breathing it... people get very sick and develop increased cancers.

    It is horrible. This is a very sad thing we have much to do to understand it and much to do to help, and much to do to try and keep it from happening again.

  6. Hey MR.V the Heat Transfer video help me understand Heat more better.

  7. 3 Things:
    1.) This is a VERY informative article. Thanks.
    2.) Does this have to do with the earthquake and tsunami in Japan?
    3.) Just wondering what the 9 Primary Questions are so I can go over them before the big test tomorrow.
    -Justin, Blue

  8. Justin, the Primary Questions have been posted on the front board since November 11... they ae REALLY hard to miss written on the Chart Paper under the sign, PRIMARY QUESTIONS, in different colors. ???

  9. Janki I 'm glad that it helped.. that's why I post these things ya know.

    (put 1 in the bonus box.)

  10. Mr. V if your website was a source towards our essay, do we need to put in MLA format and list it in our bibliography?

  11. Hey MR.V in the home text are the book author's names last and first or are they first and last. And I could not find the Publisher's name.
    Thank You!

  12. Janki

    The Primary Author/editor is Padilla, Michael

    the publisher is:

    2006, Pearson Education Inc. Upper Saddle River, New Jersey.

  13. MRV BEACH TEACH BLOG is a website and the archive title is the Webpage.

    the cartoon video helped me tell the difference between temperture and heat I find those videos the best way to learn

  15. I like them too... I am glad the cartoon version helps.. Don't forget the Cartoon Guide in the classroom.

    Put one (1) in the bonus box

  16. Mr.v on the progress log it says hot stuff blog. Did that mean you just wanted us to go and read what you posted (which I did :) and I wasn't here today do I get an extra day??? Also I like the video it helped me understand heat. I like videos more I'm a good listener than a reader :)

  17. The Hot stuff blog was to help you with the "Heat is On" work sheet.

    Are you saying you like cartoons more?

  18. Yes I do like cartoons more :) and for tomorrow do you want us to bring the data table and are three observations?? Or just the data table?

  19. Oh and Sabrina/yellow

  20. YOU need both the data table and the predictions you are testing... they could be on the back if need be.
