What is specific heat capacity?
Find the Heat (q). A piece of Iron with a mass of 25 grams has a specific heat of .460. How much heat will be released if the temperature is raised from 10 degrees Celsius to 25 degrees Celsius.
What is 172.5 J?
Name the type of heat transfer responsible for the scenario: The sun's energy reaches Earth from millions of miles away.
What is radiation?
The three common types of heat transfer are __, ___, and ___.
What is conduction, convection, and radiation?
Substances that have a high specific heat require ___ to raise their temperature.
What is more energy?

What is 4.8 grams?
Name the type of heat transfer responsible for the scenario: A house's attic is always warmer than its basement.
What is convection?
Heat and temperature are different.
What is temperature measures average kinetic energy of the particles of an object and heat describes the flow of energy from warmer places to cooler places due to difference in temperature.
