Temperature
This is the temperature in Fahrenheit that water freezes.
32*
This material can easily transfer heat energy.
Conductor
In the formula Q=m x c x Δ T this is the quantity that represents Q.
Heat Energy
These are the two main types of heat engines.
Internal and external combustion engines
This states that absolute zero cannot be reached
The third law of thermodynamics
This is slower in gasses because the particles are farther apart and do not collide as often
Conduction
This is the temperature in Fahrenheit that water boils.
212*
This type of material does not transfer heat energy easily.
Insulator
In the formula Q=m x c x Δ T this is the quantity that represents c.
Specific Heat
Most heating systems use this to distribute thermal heat
Convection
This law states that energy is conserved.
The First Law of Thermodynamics
This is thermal energy that is not converted into work
waste heat
Mercury thermometers work on this principle.
Thermal expansion
This type of thermal energy transfer takes place mostly in Fluids.
Convection
The rate at which materials radiate energy increases as this increases
The objects temperature
Because thermal energy is not transferred to the environment these are considered to be closed systems.
Calorimeters
This second law of thermodynamics states that energy can flow from cold to warm objects only if this is done.
work is done on the system
To maintain even room temps these systems use fans to circulate warm air from a furnace through filters and ducts to the rooms of a building
Forced - Air Heating
In science this is the most used unit for temperature.
Celsius degree
This type of energy transfer requires objects to be in contact with each other.
Conduction
The lower the specific heat of a material the the more this rises with a given amount of energy is absorbed by a given mass.
Temperature
This can be used to stop convection and conduction from transferring heat to a liquid inside a thermos bottle.
a Vacuum
The conversions between thermal energy and other forms of energy is called thiss
Thermodynamics
Warm fluid rising to displace cooler fluids to lower positions until it is heated and rises again is an example of this
Convection current
Thermal energy depends on mass, temperature and this of an object
phase of matter
Energy from the Sun reaches Earth mostly by this
Radiation
Heat pumps must do work on this to reverse the normal flow of heat through an object.
Refrigerant
In most automobiles engines, the linear motion of the strokes is turned into this type of motion by the crankshaft.
Rotary
An object transferring energy to its surroundings is considered this type of thermal transfer.
Positive
Temperatures in heating systems are regulates using this devices.
