Measurement
what is temperature?
temperature is the measure of the average kinetic energy
what is coduction?
a method of heat transfer that incudes solids and direct contact
Adding heat makes particles move ______?
Faster
A measure of how hot or cold something is
What is temperature?
The transfer of heat between particles as they collide within a substance or between two objects in contact.
What is conduction?
energy can neither be created nor destroyed, it changes from one form to another.
what is degree Celsius ?
unit for measuring temperature
which has a higher specific heat, water or iron nail?
water
which has a higher thermal energy, a warm bath tub or hot cup of coffee.
bath tub
0 degrees
What is the freezing point of salt water in fahrenheit?
absolute zero is equal to ............k
0
What is specific heat?
As particles move faster, they _______ with each other with greater force.
Collide
A material that is a poor conductor of heat energy.
What is an insulator?
what is meant by convection
it is a way where heat is transferred in liquids and gasses .
what is meant by thermal energy
the measure of the total kinetic energy in an object.
Whenever heat flows into or out of a system the gain or loss of thermal energy equals the amount of heat transferred.
What is the 1st law of thermodynamics?
When an object starts moving, its potential energy becomes turns into?
What is kinetic energy
The transfer of thermal energy. (Thermal energy moving from one place to another)
What is heat?
100 degrees
what is the boiling point in celsuis
The amount of energy needed to raise the temperature of 1 kiolgram of water by 1 degree C. what does this definition represents?
specific heat
what is meant by heat
it is the transfer of thermal energy
Heat will always be transferred from areas of high temperature to areas of lower temperature until both objects become the same
What is thermal equilibrium?
Theoretical temperature at which molecules stop moving and no more heat can be removed from the object.
What is absolute zero?
mention 2 examples of heat insulators
wood and plastic
