warmer object, cooler object
When objects are at different temperatures, energy is transferred from the ___________________ to the ___________________.
_____________________ is a measure of the average kinetic energy of all the particles in an object or substance.
Temperature does not depend on the __________ or the type of particles in a ________________.
_______________ is the measurement of the total amount of kinetic energy of all the particles in an object or substance.
faster, thermal energy
When an object is hot, its particles are moving _________________ and it has more ___________________ than it has when it is cold.
_____________ particles move much faster and have more energy than ______________
Similarly, the particles in a __________ have more energy than the particles in the liquid phase of the same substance.
mass, composition, state, and temperature
The thermal energy in any object is related to its ________, its _______________, its ______________, and its ____________.
_____________ is the energy that is transferred between two objects that are at different temperatures.
When thermal energy is transferred to an object as heat, the average ______________________ of the particles of the object will increase.
