water that is underground
What is groundwater?
the energy that an object has because it is moving
What is Kinetic Energy?
a number that summarizes a set of data and that can be computed by adding all the numbers in a list and then dividing by the number of numbers in the list
What is Average?
the ability to make things move or change
What is energy?
Why was the thermometer so famous?
It had many degrees.
a measure of how hot or cold something is
What is temperature?
when something stays mostly the same over time
What is stability?
to make something safe to eat or drink by heating it
What is pasteurize?
Engineers design computers to cool down quickly so they do not break. What happens to the molecules in a computer when the temperature of the computer decreases?
The energy of the molecules in the computer decreases.
Why can't you trust an atom?
They make up everything.
tiny organisms that are made of a single cell
What is bacteria?
a heating unit that stores and warms water
What is a water heater?
to move from one object to another or one place to another
What is transfer?
After a candle is blown out, the wax of the candle decreases in temperature. What happens to the molecules of the wax when the temperature of the wax decreases?
The energy of the molecules of the wax decreases.
DOUBLE JEOPARDY: Which is faster: heat or cold?
Heat. You can catch a cold.
anything that has mass and takes up space
What is matter?
DOUBLE JEOPARDY: a balanced state in which a system is stable, such as when two or more samples are at the same temperature
What is equilibrium?
a group of atoms joined together in a particular way
What is a molecule?
Nistu is cooking rice in a pot. When she leaves the pot on the stove for a while, the temperature of the rice increases. What happens to the molecules of the rice when the temperature of the rice increases?
The energy of the molecules in the rice increases.
Why is electricity so dangerous?
It doesn't know how to conduct itself.
to reach a conclusion using evidence and reasoning
What is infer?
a set of interacting parts forming a complex whole
What is a system?
the total kinetic energy of all the molecules that make up a sample
What is thermal energy?
In some places, hot water from underground can shoot up into the air through a hole in the ground. When this happens, the ground surrounding the water increases in temperature. What happens to the molecules in the ground when the temperature of the ground increases?
The energy of the molecules in the ground increases.
Why is it always so hot in the corner of a room?
Because a corner is 90 degrees.
