Worksheet on heat, temperature, and specific heat.
Complete the questions below in your chemistry notebook or Google doc (share with azarley@morrishs.org
). Use complete sentences.
1.
Explain the 3 factors that must be considered when calculating heat? Think about which block of ice would take more energy to melt a 50 pound block of ice versus a 100 pound block of ice.
Think about how much energy is needed to heat your pool up 10 degrees Fahrenheit versus 20 degrees Fahrenheit. Think about what takes more energy to heat up the water inside the pot or the metal holding the water?
2.
Explain heat transfer between objects. Use an analogy of you touching something that feels warmer or cooler and what happened next and why?
3.
What is the difference between heat and temperature? Think about the units, think about an example of how much energy does it take to heat up small pot of water compared to a large pot of water to boiling? Which one takes more heat and why? What is the temperature of the small and large pot of water at boiling?
4.
What is the difference between a Celsius unit, Kelvin unit, and Fahrenheit unit of measure? Think about what temperature water freezes and boils on each one of those scales and compare the increments between freezing and boiling. When using the heat equation what units of temperature can be used interchangeably and why?
5.
When we want to indicate how hot or cold something is what unit of measurement is used?
6.
When we want to indicate how much energy is in a substance or system what unit of measurement is used?
7.
Use your life experiences and provide an analogy of two or more substances that have different specific heats. Explain those differences. Look up the specific heat of the substances(only if a pure substance) used in your example. Provide units for the specific heat. Provide a unique example based on your life experiences! Do not use an example already discussed in class or in the textbook. BE ORIGINAL
8.
Provide a definition for specific heat in your own words .
9.
If you are heating something on the stove and keeping a spoon in the pot to stir the contents what spoon is better suited for the task, a wooden or metal spoon? Explain your choice. Look up the specific heat of steel and oak.
10.
Explain conduction
11.
What is an insulator? Provide some examples of insulators. How does the specific heat of an insulator compare to the specific heat of a good conductor?

12.
Explain equilibrium temperature based on this analogy, forging metal to make a horseshoe, the metal is heated in a blast furnace until malleable enough to be shaped to fit the horse hooves, the hot metal is then placed into water. Think about the transfer of energy from the horseshoe to the water and what happens to the temperature of both objects. Think about what the initial and final temperature is of both objects.
13.
Record the heat(q) equation. Label the units of measurement.
14.
What equation would be used to solve for equilibrium temperature in the horseshoe analogy (See
?#12)? Think about the data needed to find equilibrium temperature in the horseshoe analogy.
