- 1Kinetic Particle Model1. All matter is made up of small particles
2. All collisions are perfectly elastic
(sum of Kinetic energy initial = sum of Kinetic energy final)
3. Potential energy is stored in the intermolecular bonds - 2define thermal energyamount of heat an object is emitting or receiving via a thermal conductor
- 3define temperaturethe average kinetic energy of particles in a substance
- 4kinetic energyenergy related to the movement of a substance
- 5define heatthe energy in the process of being transferred
- 6define internal energyEK+EP=EI
- 7define conductiontwo things touching (from hotter object to the cooler object)
- 8define radiationtransfer of energy through photons (doesn't need a medium)
- 9define convectiontransfer of energy due to the motion of a fluid or gas
- 10what is the change of temperature due tothat a change in temperature is due to the addition or removal of
energy from a system (without phase change) - 11define specific heat capacitythe amount of energy needed to increase 1 kilogram of a material by 1 degree Celcius
Directly proportional - 12define thermal equilibriumtwo systems have equal temperature and therefore the same kinetic energy
- 13laws of thermodynamics (1,2)1. conservation of energy Qin=W
(Qin=energy in the system, W=work done by the system)
2. Entropy - the measure of disorder in a system increases over time. A disordered system cannot be used. So, heat does not spontaneously pass from a cold body to a hot body - 14laws of thermodynamics (3, zeroth)3. the maximum entropy of a system comes when the temperature reaches absolute zero.
Zeroth. If two systems are in thermal equilibrium with a third system, then they must be in thermal equilibrium with eachother - 15what is the change in the internal energy of a systemthe change in the internal energy of a system is equal to the energy
added or removed by heating plus the work done on or by the system, and
recognise this as the first law of thermodynamics and that this is a
consequence of the law of conservation of energy - 16define efficiencypercentage of energy that is used
- 17describe the nuclear model of the atomcharacterised by a small nucleus
surrounded by electrons - 18strong nuclear forcebinds the nucleons in the nucleus together
