Solving heat problems/formula
The amount of energy required to raise the temperature of 1 gram of a substance by 1 degree Celsius
specific heat
energy (heat)=(mass)(specific heat)(x)? What is x?
What is change in temperature
When energy is transferred through touching.
Conduction
what is thermodynamics?
What is the study of the effcts of work,heat and energy on a system.
thermal energy
What is the energy generated and measured as heat
work is transfer of
What is energy
Air is a good _____________
What would happen if an object reached absolute zero.
All movement would cease.
temperature is
the measure of the kinetic energy of molecules within a substance
absolute zero
where all movement ceases (0 K)
If a cup of coffee is 80 degrees Celsius and an ice cube is added, how does heat flow?
from the coffee into the ice cube
Transfer of energy through waves.
Radiation
3rd law of Thermodynamics
What is no system can reach absolute zero

What is .839
heat
What is a form of energy that is transferred by a difference in temperature
if the mass of a moving object is doubled,thermal energy will?
double
When warm air is moved through a system to heat an object.
Convection
__________ lost= ___________ gained because energy is conserved
What is heat and heat
convert 305 K to the Celsius scale
What is 32C
1st law of thermodynamics
Energy lost by a system must be gained by something else in the system
When an object is heated it tends to ____________.
expand
This type of energy transfer is done by the sun
radiation
This is the reason a refrigerator or an air conditioning unit works.
Work is done on the system so that cold air is put into a hot place.
