A thermometer in a sample reads 25 °C. What is the sample's temperature in kelvins, Ari?
A thermometer in a sample reads 100 °C. What is the sample's temperature in kelvins, Bo?
A thermometer in a sample reads -20 °C. What is the sample's temperature in kelvins, Esme?
4.
In the energy bar chart, which particle store grows as the water warms, Jun?
- Neither, since warming adds no energy
- Particle kinetic energy
- Particle potential energy
5.
In the energy bar chart, how much energy was added to the water, Kira?
Use the picture in question 4.
- 600 J, the new kinetic bar
- 300 J
- 1100 J
6.
In the energy bar chart, what does the taller kinetic bar mean for the water's particles, Luz?
Use the picture in question 4.
- They move faster on average
- They have become bigger than before
- They stop moving
7.
A squeezed spring stores energy. At the particle scale, where is that energy stored, Noah?
- In heat inside the coils
- In particles pushed closer together
- In the spring's motion
8.
At the particle scale, where is the chemical energy in a battery stored, Pia?
- In how its atoms are bonded
- In the battery's height
- In the particles' speed
9.
What happens to particle motion as a sample is cooled toward 0 K, Tala?
- It speeds up
- It stops at 0 °C
- It slows toward a minimum
10.
Do the particles in ice at 0 °C still move, Zee?
- No: frozen particles stand still
- Yes: 0 °C is 273.15 K
- No: 0 °C means no motion

Motion energy and stored energy of particles. Every version has 10 questions, and the answer key prints on the second page.

I can convert °C to kelvins (K = °C + 273.15) and explain absolute zero. Particles still move at 0 °C.
I can say that temperature tracks the particles' average kinetic energy. The ratio of two gas energies is the ratio of their kelvin temperatures, and the average kinetic energy is (3/2)kT.
I can explain stored energy at the particle scale. Springs and rubber bands store energy in particle spacing; chemical energy is stored in bonds and arrangements; melting raises particle potential energy at a steady temperature.
I can tell temperature (an average) from thermal energy (a total that grows with the amount of matter).

Standard: HS-PS3-2

particle kinetic energy: Energy of particles' motion; thermal energy

particle potential energy: Energy stored in how particles are placed or bonded

kelvin (K): Temperature counted from absolute zero; K = °C + 273.15

absolute zero: 0 K, where particle motion is at its lowest

change of state: Melting, freezing, boiling: particles move apart or together

Your child subtracted 273.15. Kelvin temperature is the Celsius temperature plus 273.15.

Your child thought particles stop at 0 °C. Particles slow toward their least motion only near absolute zero, 0 K, which is −273.15 °C.

Your child divided Celsius temperatures. Particle kinetic energy follows kelvin temperature, so change to kelvins first.

What is the most common mistake with motion energy and stored energy of particles?

Your child subtracted 273.15. Kelvin temperature is the Celsius temperature plus 273.15.
