Thermal Energy One
A system that does not exchange matter or energy with the environment is THIS type of system.
What is a CLOSED system?
An OPEN system exchanges either MATTER or this with the surrounding environment.
What is ENERGY?
As this factor increases, the change in temperature will decrease for the same energy input.
What is MASS?
All Aboard! An object that transfers thermal energy easily is called this:
What is a CONDUCTOR?
This type of energy transfer allows the sun to warm the Earth.
What is RADIATION?
When thermal energy is transferred, the object that provides the energy is called this:
What is the SOURCE OBJECT?
THIS object accepts energy in a thermal transfer, making it warmer than it originally was.
What is the RECEIVER object?
In THIS proportional relationship, an increase in one factor, yields an increase in another factor. (image C2)
What is DIRECTLY proportional?
THIS is a material through which thermal energy does not flow easily.
What is an INSULATOR?
This type of thermal energy transfer is thought to occur in the mantle of the Earth.
What is CONVECTION or CONVECTION CURRENTS?
The amount of thermal energy moving from a region of higher temperature to a region of lower temperature is known as this:
What is HEAT?
The transfer of thermal energy from one material to another by electromagnetic waves is called this:
What is RADIATION?
In THIS proportional relationship, an increase in one factor yields a decrease in another factor. (image C3)
What is an INVERSE or INVERSELY proportional relationship?
Think Fast! The particles in a thermal conductor move easily so THIS is transferred easily.
What is KINETIC ENERGY?
Copper has THIS characteristic making it useful as a base in a teakettle.
What is a LOW SPECIFIC HEAT?
The transfer of thermal energy due to the collisions of particles is called this:
What is CONDUCTION?
The transfer of thermal energy in liquids and gases (but not solids) by the movement of particles is called this:
What is CONVECTION?
Objects with a large amount of THIS have a greater amount of energy transfer with the environment.
What is SURFACE AREA?
As mass increases, the amount of energy required to increase its temperature does THIS.
What is INCREASES or GOES UP?
On a hot sunny day you might prefer white colored clothes because of THIS property of thermal energy transfer.
What is REFLECTION?
When the temperatures of materials that are in contact are the same, the materials are said to be in this state:
What is THERMAL EQUILIBRIUM?
Hot water is poured into a mug. The mug gets hot. This is an example of what kind of thermal energy transfer?
What is CONDUCTION?
THIS property of a material can affect how much thermal energy it absorbs.
What is COLOR?
The amount of thermal energy required to increase the temperature of 1 kg of a material by 1°C is called this:
What is a material's SPECIFIC HEAT?
The ocean is cold throughout the summer because water has THIS.
What is a HIGH SPECIFIC HEAT?
