**Temperature Conversions**

**Kelvin Scale**

The Kelvin scale is the only scale that has an absolute zero.

*Celsius Scale*

The Celsius scale is what we commonly use in the science classroom.

__Comparisons__

Boiling point = 100 C and 373 K

Freezing point = 0 C and 273 K

Notice that they are seperated by 100

Absolute Zero = -273 K and 0 K

You must know this formula..but don't worry, it's on you Reference tables!

K = °C + 273

Practice Problem

What kelvin temperature is equivalent to 35 degrees Celsius?

K = °C + 273

K = 35 + 273 = 308

**Measurement
of Heat Energy**

The amount of heat given
off or absorbed in a reaction can be calculated using the following equation:

*q = mC**D**T*

*q = eat (in joules)*

*m = mass of the substance*

*C = Specific Heat
Capacity of Substance*

*DT = (initial Temp - Final
Temp)*

*So
What's Specific Heat Capacity?*

*Specific Heat Capacity is the amount
of heat required (in joules) to raise 1 gram of the substance 1 degree celsius.*

*Listed below is a table of Specific
Heat Capacities for some substances. Notice that water has a very high value...ever wonder why your pool takes
so long to heat up???*
