Energy
What is the measure of the ability to do work?
100
KE = 1/2 mass X velocity squared
What is the equation to calculate kinetic energy
100
Why is -10 K impossible
O K means no motion; there can be nothing lower than no motion

heat is released as the compressed gas becomes a liquid
What is the source of the warm exhaust from a refrigerator or air conditioner
200
energy must be added to form a gas
What is evaporation
200
nonmechanical/mechanical
What is the energy of vibration of the individual atoms that make up the softball and the energy of the motion of the ball as it is thrown.
200
photosynthesis
What is the process of plants that convert solar energy to chemical energy.
200
absolute zero
What is temperature when the particles of a substance exhibit no motion.
200
Heat is removed as the air molecules inside the refrigerator collide with the(wall of the refrigerator) liquid refrigerant
What is the cause of the cool air inside of a refrigerator
300
endothermic process
What is a process in which energy is taken from the environment
300
PE = mgh
What is the equation to calculate the stored energy of an object due to its position
300
atomic bonds
What is source of chemical energy stored in molecules
300
heat
What is the energy transferred between particles of 2 objects due to a temperature difference between the 2 objects
300
IN a passive solar heating system solar E is absorbed by a rooftop panel in active solar heating a pump is used to distribute the heated water.
What is the difference between passive solar heating and active solar heating
400
all particles are always in motion, larger molecules move slower, increase temp increase motion
What is the kinetic theory

392 J
400
nuclear fusion
What is the source of the sun's Energy
400
which transfers more E; 1 kg water at 10 deg C and freezer at -15 deg C or 1kg water at 60 deg C in an oven at 65 deg C
1kg of water at 10 deg C and a freezer at -15 deg C C
400
the process of changing the liquid refrigerant to a gas takes heat from the air and food inside the refrigerator
What is the cause of cold air/cold food inside your refrigerator
500
temperature
What is the average kinetic energy of molecules
500
Average size of crater dependent on mass of sphere
What is the title of a graph created from data collected when students were experimenting with mass of spheres and the size of craters created by the spheres once the sphere was dropped.
500
sound energy, heat energy
What is the transformations of energy other than PE to KE once an object is dropped.
500
