the sum of the kinetic and potential energy of all the particles that make up an object
thermal energy that flows from something at a higher temperature to something at a lower temperature
amount of thermal energy needed to raise the temperature of 1 kg of some material by 1°C
particles are packed closely together and are constantly vibrating in place- strong attractive forces hold particles in place
attractive forces between particles are weaker than in a solid and can slide past each other- attractive forces are strong enough to cause particles to ling together- definite volume but not definite shape
particles are far apart and attractive forces between them are weak-particles do not cling together- no definite shape or volume
made of electrically charged particles-matter consisting of positively and negatively charged particles and does not have a definite shape or volume
the transfer of thermal energy by the movement of warmer and cooler materials occurs in a fluid by the movement of fluid from place to place
forms when the air around matter cools enough so that water vapor in the air changes to a liquid
temperature increases, particles in liquid move faster and become farther apart and no longer cling together- vaporization occurs as liquid changes into gas- can occur within the liquid or at the surface of the liquid
