Mrs. Franzetti
Where did Mrs. Franzetti go to college?
How can you show that particles are moving?
By adding motion lines on the spheres.
What determine if matter is a solid, liquid, or gas? Which one is correct?
1. The number of particles.
2. The movement of particles.
3. The size of the particles.
2. The movement of particles.
False. Thermal energy (Heat) moves from objects of higher temperatures to objects of lower temperature.
What is specific heat mean? (Hint page 82)
The amount of thermal energy required to increase the temperature of 1 kg of a material by 1 degree Celsius.
What is Mrs. Franzetti's child named?
Shylo.
How does liquid particles move?
They move in a random motion, sliding past each other.
What is boiling?
Liquid to Gas
What is Conduction?
When thermal energy moves from particles in a solid.
Which substance is the best at conducting thermal energy?
A - Foam Container
B - Mug
C - Soda Can
C. Soda Can
What did Mrs. Franzetti teach before teaching Science and Social Studies?
Music
How does thermal expansion occur?
Heat (Kinetic Energy) is added.
What is condensation?
Gas to Liquid
What is Convection?
When thermal energy moves from particles in liquid or gases.
You can bak food in either a metal pan or an oven safe glass. Which would require more energy to heat up?
The glass dish would require more energy to heat up because it has a higher specific heat.
How many pets does Mrs. Franzetti have?
2 Cats
Why does trash smell worse in the summer vs. in the winter?
It smells worse in the summer because the heat adds kinetic energy to the particles, making the particles move faster apart, and reach our noses faster.
How does potential energy increase?
Potential energy increases as the distance between particles increases.
Give me a real life example of Convection.
Some answers could include: A lava lamp, A toaster warming the air around it, Ocean, Magma.
If I am wearing a white shirt, will I absorb heat faster, or slower than someone wearing a black shirt?
HAH. Trick question. Using everything we've learned so far, why does popcorn pop?
Examples: Thermal energy is transferred to the popcorn by radiation from a microwave, or conduction in a pot on a stovetop. Water particles in the popcorn speed up. As they speed up, they start to move farther and farther apart until the water becomes a gas. As the gas goes through thermal expansion inside the kernel, the popcorn then bursts open.
How does mass affect the total energy?
More mass will contain more total energy.
What happens to the temperature of matter when a phase change occurs?
The temperature stays the same, as that energy goes into changing the state of matter, rather than raising the temperature.
How does putting a popsicle in the freezer, freeze the popsicle?
Why does the sauce on a hot pizza burn your mouth but the crust of the pizza does not burn your mouth?
Even though they both have the same temperature, the pizza sauce has a higher specific heat. Sauce has water in it. It's still hot, vs. the crust has a lower specific heat, which means it does not take as long to cool down.
