Vocab 1
The change of state of particles from a gas to a liquid
Condensation
Energy transferred from a hotter object to a cooler object
Heat
Brazil is 90 degrees and Chicago is 50 degrees. Who has a higher kinetic energy?
Brazil
A substance that flows and keeps no definite shape because its molecules are loosely packed and constantly moving. It takes the shape of its container but maintains constant volume.
Liquid
What is it called when a liquid becomes a solid?
Freezing
The transfer of energy from one part of a material to another or between two objects that are in physical contact with each other
Conduction
Describes two quantities that are related by a simple ratio
Proportional
Antarctica is -136 degrees and Death Valley is 134 degrees. Where is there less kinetic energy?
Antarctica
A substance that can only be contained if it is fully surrounded by a container (or held together by gravitational pull); a substance whose molecules have negligible intermolecular interactions and can move freely.
Gas
Is energy absorbed or released in the following situtation?
Frozen puddle melting
Absorbed
The change of state of particles from a liquid to a gas at the surface of the liquid
Evaporation
The weather conditions prevailing in an area in general or over a long period.
Climate
How do you know if an object has more kinetic energy then another?
The object will be warmer.
The warmer object has more kinetic energy.
A substance that retains its size and shape without a container; a substance whose molecules cannot move freely except to vibrate.
Solid
Is energy absorbed or released in the following situtation?
Dew forming on grass
The transfer of energy caused by the circulation of matter due to differences in density
Convection
The energy an object has due to its motion
Kinetic energy
My hand is 37 degrees and the hot coco is 95 degrees. Where is the energy moving?
The energy is moving from the coco to my hand.
What is it called when a solid becomes a liquid?
Melting
Is energy absorbed or released in the following situtation?
Puddle Freezing
Released
A measure of the average kinetic energy of the particles of a substance
Temperature
The transfer of energy by light
Radiation
The snow ball is 0 degrees and your hand is 37 degrees. Where is the energy moving?
The energy is moving from the hand to the snow.
What is it called when a gas becomes a liquid?
Condensation
Is energy absorbed or released in the following situtation?
Dew Evaporating
Absorbed
