Explain how energy is transferred when you hold a cold glass of water.
What is the heat from you hand gets transferred to the glass.
What is the main difference between heat and temperature?
Heat is energy in transfer/ waves, while temperature is a measure of average kinetic energy.
What is the difference between conduction and convection?
Conduction is the transfer of energy through direct contact in solids while convection is heat transfer through cycles in air/ liquid.
Give an example of a phase change you observe in your daily life and explain what happens to the particles during this change.

*Daily DOUBLE* What are the 4 points of the Particle Model of Matter
1. Everything is made up of particles
2. Particles have spaces between them
3. Particles are always moving
4. When heat is added, the particles move faster
What are the 3 types of energy transfer?
What are, Conduction, Convection, and Radiation
What does the R value of insulation tell us?
Describe how the Particle Model of Matter explains the difference between the states of matter (solid, liquid, gas) any provide a diagram.
The Particle Model of Matter explains that in solids, particles are tightly packed and vibrate in place. In liquids, particles are close but can move past each other, allowing the liquid to flow. In gases, particles are far apart and move quickly in all directions. This difference is caused by the understanding that as particles heat up they gain more energy.
