Vocabulary
What do we call the energy an object contains due to its motion?
Kinetic Energy
Which type of thermal energy transfer occurs through direct contact?
conduction
mass, composition, state, and temperature
If you hold a glass of cold water, what direction is the energy flowing?
a) from your hand to the glass
b) from the glass to your hand
a) from your hand to the glass
because energy always flows from warmer object to cooler objects
What do we call the transfer of thermal energy through electromagnetic waves?
Radiation
Convection
There is a pot of soup on the stove. What are two ways that you could increase the thermal energy of the soup?
Increase mass (add more soup)
Increase temperature (heat it up)
Can two objects that are the same temperature and made of the same substance have different amounts of thermal energy? If so, how?
YES
Name an instrument that measures temperature
Thermometer
The sun, a lamp, and a microwave are all examples of what type of thermal energy transfer?
Radiation
A baby an an adult are both 98.6 degrees Fahrenheit. Do they have the same thermal energy? Explain why or why not
No, they do not. The adult has more mass so the adult will have greater thermal energy.
What happens to particles as they heat up?
The average kinetic energy of the molecules in a material
Temperature
Warm water rises, and the cooler more dense water sinks. What type of thermal energy transfer is this?
Convection
What has more thermal energy: an iceberg the size of a building or a cup of boiling water?
The iceberg.
Does every object have thermal energy?
Yes. Even very cold objects have thermal energy.
