Lesson 3 Concepts
Where does thermal energy go?
Energy flows between the source object* and the receiver object*. Or from hot to cold!
The object that provides energy for the energy transfer
Source object
How does mass affect the change in temperature of a substance? As mass increases, the change in temperature _______________.
It takes more energy from the surroundings to increase the kinetic energy of the particles if there are more particles. As mass increases, the change in temperature will decrease…
The measurement of heat
Temperature
Robyn Fenty is the name of which singer?
Rihanna
transfer of thermal energy from one material to another through electromagnetic waves
Radiation
The object that gains the energy from the energy transfer
Receiver object
An object with a higher specific heat will take (less/more) time to heat up?
More
A material in which thermal energy does not transfer easily
Insulator
What is the capital of PA?
Harrisburg
Which state of matter does convection not occur in?
Solids
When the temperatures of materials that are in contact are the same.
Thermal equilibrium
A small, deep bowl would loose thermal energy (faster/slower) than a wide, shallow bowl.
Slower
A material in which thermal energy flows easily
Thermal conductor
What document was signed in 1776
Declaration of Independence
Exchanges matter and energy with the environment
Open system
Transfer of thermal energy between materials by the collision of particles (Direct contact!!)
Conduction
A thin pancake will loose thermal energy (faster/slower) than a thin pancake
faster
The amount of thermal energy required to increase the temperature of a 1kg material by 1 degree C
Specific Heat
Which animal eats eucalyptus leaves?
Koala
Does not exchange matter or energy with the environment
Closed system
transfer of thermal energy by the movement of particles from one material to another
Convection
A student wearing a white shirt will gain thermal energy (faster/slower) than a student with a black shirt.
slower
Total energy of a system that is dependent on the number of particles in a system, state of matter and the temperature.
Thermal energy
Which organ is the largest?
Skin
