Energy and Motion
the energy that an object possesses due to its position. The energy stored in the bonds of atoms.
What is potential energy?
The molecules of a substance get more energetic as the ______________ increases.
What is temperature?
Transfer of thermal energy by waves
What is Radiation?
This is the amount of energy required to raise the temperature of 1 gram of water 1*C.
What is a calorie?
What phase change has molecules in this state of matter move the fastest.
What is a gas?
FOR DOUBLE MONEY (total of $400)--
There is a plateau (flat part) on a heating curve because..
What is all of the energy is being put into the substance to change state, so the temp stays the same.
Transfer of thermal energy between materials by collision of particles. (if the particles are colliding, they are touching)
What is a conduction?
The name for the full-size numbers before a group tell us about the whole group:
2CH4 + 2H3O → 2CO + 7H2
What is a coefficient?
a flow of energy due to temperature differences
What is heat?
When a bowl of cold soup is heated, the thermal energy is increased. Heating the soup causes its molecules to ________. (move faster, move slower)
What is move faster?
You are roasting marshmallows with wire coat hangers and you leave the hanger in the fire for ten minutes. What happens to the end you were holding onto and WHY (molecular)?
What is "The end heats up because the heat from the fire causes the molecules in the hanger to heat up and vibrate faster. These molecules collide with the ones next to them which in turn begin vibrating faster, all the way up to the end of the wire." ?
what transfers energy by the movement of large numbers of particles in the same direction within a liquid or gas.?
What is Convection?
The formula for density.
What is mass over volume?
The energy of motion. The breaking of the bonds of atoms
What is kinetic energy?
Heat moves from ______ to _______objects.
What is hot to cold?
This instrument is used to measure the temperature of a liquid.
What is a thermometer?
The specific heat movement of rocks in the mantle of the earth is called?
What is Convection?
How did our continents move out of pangea?
What is plate tectonics?
In this state of matter molecules only vibrate back and forth.
What is a solid?
The measure of the average kinetic energy of all the particles in the object
What is the temperature?
Would heat be able to flow between two warm cupcakes from the same batch that are touching on a cooling rack?
What is NO! They are the same temperature so no heat flow takes place.
The law of conservation states:
What is matter cannot be created nor destroyed?
