How is heat transferred from the stove to the pan?
conduction
convection
radiation
temperature
Sam placed a glass of water in the refrigerator. After about an hour he took it out and found it to be colder.
What is the most likely thing that happened?
the cold that was in the refrigerator transferred into the water
the particles in the water started to move faster
the cold from the refrigerator radiated into the glass
the heat that was in the water transferred out into the refrigerator
What is the scientific definition of temperature?
Temperature is how hot or cold something is
Temperature in Celsius
Temperature in Fahrenheit
Temperature is the speed of the molecules in an object
Think about a pan of water sitting on an electric stove. The stove is then turned on to high.

The First Law of Thermodynamics
The change in internal energy of a system equals the difference between the heat taken in by the system and the work done by the system.
The change in energy of a system is the sum between the heat taken in by the system and the work done by the process.
The internal energy of a system equals the difference between the heat taken in by the process and the work done by the process.
