thermal energy

The total energy of all the particles of an object.

heat

The energy transferred from a hotter object to a cooler one

Temperature

a measure of the kinetic of the particles in a substance

transfer

to move from one object to another

absolute

definite or without question

All objects are made of

small particles

are the particles of an object constantly in motion? what does this mean?

yes, kinetic energy

particles are arranged in special ways in different objects, so they also have

potential

object contain thermal or internal energy even if they

do not feel hot

as the warmer object cools down, the cooler object warms up until______ when this happens, heat

the two objects are the same temperature, stops transferring between the objects

when an object is at a higher temperature, the particles ______

move faster and have a greater average KE than when the substance is at a lower temperature

thermometers

show how hot or cold something is compared to a reference point

the kelvin is the

si unit of temperature

different objects at the same temperature can have

different amounts of thermal energy

other factors include the potential energy and arrangement of particles, as well as

states, types, and amounts of matter

during a change of state, the thermal energy of a substance

changes, but the temperature is the same

the amount of matter in an object affects its

thermal energy

because more matter means

more particles

what if the object contain the same amount of matter?

the object at the higher temperature has more thermal energy

an objects change in temperature depends on the

environment and types of matter in the object

the minimum value for the kelvin temperature scale and what would happen

0, no KE so motionless

facts that determine thermal energy

mass,heat,change in temperature, KE,PE, arrangement of particles

Can you tell for certain which soup will require more thermal energy

no because it doesnt only depend on size but also the matter

as thermal energy increases, the particles ____ the ke of the particles didnt change, so the temperature..

change, stays
