ESSENTIAL QUESTIONS
Please go to the following sections and write down the essential questions and
provide a thoughtful answer for each. Please record all these questions within your
science journal:
Heat and Temperature:
• What is the difference between heat and temperature?
• What happens to the molecules of a substance when heat is added
to it?
• Which types of measurements are used to describe quantities of
heat and temperature?
• How can heat be transferred from one object to another?
Convection:
• How are liquids and gases affected by heat?
• How is thermal energy transferred through liquids and gases?
Conduction:
• How does heat travel by conduction?
• What is thermal equilibrium?
Radiation
• What is radiant energy?
• How does heat travel as radiant energy?
NEED TO KNOW HOW TO CALCULATE:
Fahrenheit
Fahrenheit is a thermodynamic temperature scale, where the freezing
point of water is 32 degrees Fahrenheit (°F) and the boiling point
212°F (at standard atmospheric pressure). This puts the boiling and
freezing points of water exactly 180 degrees apart. Therefore, a
degree on the Fahrenheit scale is 1/180 of the interval between the
freezing point and the boiling point of water. Absolute zero is defined
as -459.67°F.
A temperature difference of 1°F is the equivalent of a temperature
difference 0.556°C.
ºC =ºF – 32/1.8000
Celsius
The Celsius scale is an interval system but not a ratio system,
meaning it follows a relative scale but not an absolute scale. This can
be seen because the temperature interval between 20 °C and 30 °C
is the same as between 30 °C and 40 °C, but 40 °C does not have
twice the air heat energy of 20 °C.
A temperature difference of 1 deg C is the equivalent of a
temperature difference 1.8°F.
Kelvin
Based upon the definitions of the Centigrade scale and the
experimental evidence that absolute zero is -273.15ºC
ºF =(ºK - 273.15)* 1.8000+ 32.00
