Heat/kinetic energy
Objects that have a lot of heat have a lot of what? (The answer is NOT temperature.)
Kinetic energy
What are the metric units for temperature?
Degrees Celsius
What lab did we do to prove that condensation on the outside of a cup did NOT come from inside the cup?
The food coloring lab
What kind of molecules can move around the easiest?
Gas molecules
The metric units for mass.
Grams
The measure of heat in a substance.
Temperature
If you are trying to keep a liquid hot or cold inside a cup, what must you do to the cup?
Insulate it
So molecules outside the cup cannot transfer their energy to the liquid inside as easily.
What is black really good at doing?
Absorbing light/heat
The device used to measure heat.
Thermometer
How does heat move?
From hot to cold.
How does a cup of cold lemonade warm up outside in the summer?
The warm/hot air outside the cup transfers its energy through the cup walls to the liquid.
What type of liquid is going to evaporate faster?
Hot liquids (because they have more kinetic energy)
Why do blankets keep us warm?
They insulate us; they don't allow our body heat to escape as rapidly
The process where water turns from a gas form to a liquid form.
Condensation
The reason why hot moves to cold.
Because hot molecules have more kinetic energy than cold ones, so they have more energy to move.
What are the standard units for temperature?
Fahrenheit
If you want condensation to occur, what conditions have to happen?
There has to be a large temperature difference between two substances.
Why do fans (not air conditioning) help keep us cool in the summer?
They allow our body heat to escape our bodies faster
The energy of motion.
Kinetic
If something is not moving, it has no...
Kinetic energy
Name three substances or materials that you could use as insulation.
Pretty much anything, including air, water, sand, wood, plastic, etc.
If you have a cold drink outside this summer on a hot day, why should you NOT wipe away the condensation that forms on the outside of the cup/bottle?
Because it could help insulate the cold drink for a little while longer
Why do we need to moisturize and drink more water in the winter?
Because cold air doesn't hold as much water vapor as warm air, so our own moisture escapes from our skin faster, dehydrating us.
The process where heat transfers from one substance to another until both substances have an equal temperature.
Thermal equilibrium
