Definitions
Temperature is a measure of______?
kinetic energy
Molecules that are cold move_________.
Slowly
Energy transfers from _______ to _______.
hot to cold
What is an example of an alphanumeric code?
apple012 (or anything similar to this with letters and numbers)
What is equilibrium?
A balanced state at which the system is stable OR when two or more samples are at the same temperature
In terms of molecules, what is the difference between smaller and larger objects?
larger objects have more molecules than smaller objects
You place a hot piece of fried chicken onto a cold plate. After 20 minutes, what will the temperature of the fried chicken and the plate be?
After the objects have been touching for a while, the chicken and the plate will be the same temperature
In Chemistry, what does 'H' stand for?
Hydrogen
In scientific terms: what does transfer mean?
To move from one object to another or one place to another.
Molecules that are hot have more __________.
The molecules keep transferring in the system until the system reaches _____________.
equilibrium
What does this statement mean: "the eagle has landed"?
extra 50 points: who coined the term?
A mission objective has been completed
by: Neil Armstrong
What does kinetic energy mean?
The energy an object has because it is moving.
What happens to food when it is warming up?
It's molecules have more energy and move faster.
Use these words: molecules, collide (collision), kinetic energy, transfer, equilibrium
to explain how energy is transferred between two objects of different temperatures and why the transfer of energy eventually stops.
Kinetic energy transfers when two objects collide. The molecules transfer energy from the hotter object to the colder object until the system reaches equilibrium.
Westridge is closest to what eating establishment?
Popeyes
What is the definition of Thermal Energy?
The total kinetic energy of all the molecules that make up a sample.
How do we calculate the average kinetic energy of molecules?
Total kinetic energy divided by the number of molecules in the system.
What happens when two objects collide?
kinetic energy transfers from the faster-moving molecules to the slower-moving molecules
