Thermal Energy & Particle Motion
Name: Period: Date:
1.Only thermal energy transfers; 'cold' is absence of thermal energy
2.Temperature measures average kinetic energy; heat is energy transfer
3.Metals conduct heat faster, so they feel cold by drawing heat from your hand
4.Energy is conserved; it transforms between forms but total amount stays constant
[!] STUDY GUIDE: Big Ideas Use to answer form questions!
1.Thermal energy is the total kinetic energy of all particles. More particles OR faster particles = more thermal energy.
2.Temperature measures AVERAGE particle speed. High temperature = particles moving fast on average, but NOT total energy.
3.Adding thermal energy makes particles move faster. This can change state: solid (vibrate) -> liquid (slide) -> gas (fly apart).
Add Energy -> Particles Speed Up -> Temperature Rises -> State May Change
THERMAL ENERGY FLOW: Energy In = Faster Particles = Higher Temperature

[?] THE PHENOMENON Write BEFORE Hook form
Why does ice melt faster in a drink than in a cooler?
An ice cube in your glass melts in minutes, but ice in a cooler can last for hours or even days. Both start at the same temperature (0C). What's different?

Q1 (NEW):
A student says "The ice is making my drink cold." Explain what's actually happening using particle motion.
Q2 (NEW):
Why does the temperature stay constant while ice is melting, even though you're adding heat?
Q3 (INTEGRATION):
Back to our phenomenon: Why does ice melt faster in a drink than in a cooler? Use thermal energy and particle motion in your answer.
