What is temperature?
Device that converts some thermal energy into mechanical energy
What is a heat engine?
SI unit(s) for temperature
What is Celsius & Kelvin?
Transfer of energy that would happen with a metal spoon in a hot pot
What is conduction?
Most common type of heating system in the United States
What is a forced air system?
Sum of the kinetic and potential energy of all the particles in an object
What is thermal energy?
Device that transforms radiant energy from the sun into thermal energy
What is a solar collector?
This type of material makes a great coolant due to the amount of energy it can absorb
What is water?
Thermal conductors work best as this type of matter
What is a solid?
Type of heating system that the school rooms have
What is a radiator system?
Energy transferred between objects due to a temperature difference
What is heat?
What are thermal insulators?
Cooler objects always cool down warmer objects.
True or false.
Type of thermal energy transfer that lava lamps work on
What is convection?
Using heating coils to heat an area
What is electric heating?
Amount of heat needed to raise the temperature of 1 kg of material by 1 degree C
What is specific heat?
Study of relationship among thermal energy, heat & work
What is thermodynamics?
A wooden bock has a mass of 20.0 kg and a specific heat of 1700 [J/(kg•˚C)]. Find the change in thermal energy of the block as it warms from 15.0˚C to 25.0˚C.
What is 340,000 J?
Convection currents from the equator cause this type of zone
What is a desert?
There are both solar and active versions of this type of heating system
What is solar heating?
Transfer of thermal energy through collisions between particles
What is conduction?
Transfer of thermal energy in a fluid by movements of warmer and cooler fluids
What is convection?
200 g of water in a glass is at 10.0°C when an ice cube is placed in the glass. What is the temperature of the water after it has transferred 4,200 J of thermal energy to the ice cube?
10.1°C
All radiation is in the form of these types of waves
What are electromagnetic waves?
This type of engine only has a 25% efficiency rate
