preparing my lessons for year 8

quick question for you all:</p>

What is the difference between heat and temperature?</p>

 

heat is a laydees magazine and temperature is a song by sean paul.

have i passed?

 

Is it that

temperature can be hot or cold but heat is usually just hot?

 

There is a fundamental difference between temperature and heat. Heat is the amount of energy in a system. The SI units for heat are Joules. A Joule is a Newton times a meter. A Newton is a kilogram-meter per second squared. Heat is transferred through radiation, conduction and convection. The amount that molecules are vibrating, rotating or moving is a direct function of the heat content. Energy is transported by conduction as molecules vibrate, rotate and/or collide into each other. Heat is moved along similar to dominos knocking down their neighbors in a chain reaction. An increase of electromagnetic radiation into a system causes the molecules to vibrate, rotate and/or move faster. With convection, higher energy molecules are mixed with lower energy molecules. When higher energy molecules are mixed with lower energy molecules the molecular motion will come into equilibrium over time. The faster moving molecules will slow down and the slow moving molecules will speed up.

Temperature is the MEASURE of the AVERAGE molecular motions in a system and simply has units of (degrees F, degrees C, or K). Notice that one primary difference between heat and temperature is that heat has units of Joules and temperature has units of (degrees F, degrees C, or K). Another primary difference is that energy can be transported without the temperature of a substance changing (e.g. latent heat, ice water remains at the freezing point even as energy is brought into the ice water to melt more ice). But, as a general statement (ignoring latent heat), as heat energy increases, the temperature will increase. If molecules increase in vibration, rotation or forward motion and pass that energy to neighbouring molecules, the measured temperature of the system will increase. </p>

Well you did ask..
</p>

Can I add

1. I already know the answer.</p>

2. Don't just copy and paste from the interweb, then claim to be all knowing.</p>

 

temperature is a measurable scale - heat is an energy form that something carries...I think! lol

 

What?

I've just read that and just hope that my Science teacher for Yr 8 whoever he/she is will be able to make that more understandable.

 

Yeah my guess would be..

that temperature is a measure used to measure how much heat (a form of energy) there actually is.

Always hated science. ff

 

Do I ask you to do my work for me?

 

Answer

Temp describes how hot or cold an object is, and is usually measured in degrees Celsius.</p>

Heat is a form of enery and, like all energy, is measured in joules (j).  Another name for heat energy is thermal energy.</p>

 

RE: Can I add

</p>

Dam did it show that much.. </p>



</p>

 

just a tad

I'm sold on the beer piccy though.  Stella it is</p>

 

ive just prepared my coaching plan for next monday.
id rather do one for science.

 

What do you coach + where?

 

RE: What do you coach + where?

coach fishing at an activity centre for kids with behavioural/learning and general lets be a difficult twit difficulties.
Otherwise known as the kids teachers refuse to help.

 

RE: What do you coach + where?

Just give 'em a good slap!

 

RE: What do you coach + where?

doesnt quite work like that unfortunatley.
To be honest, you'd be quite suprised how well behaved these 'disruptive kids' are

 

taxi drivers

do know everything though

don't they?

 

'Kids teachers refuse to help'

</p>

Well why don't you go and train to be a teacher, and see how you cope.</p>

 

RE: Answer

Heat is a form of energy...Temperature is a degree of hotness.
