energy production
What method of energy produces the most energy production and the least pollution.
Nuclear energy
when energy changes from one form to another it is called what?
energy transformation
Gas
True or false No energy is gained or lost during the collision between molecules.
true
Can momentum be hidden to human eyes like how kinetic energy can be hidden as heat?
no
what form of energy production causes thermal production
Nuclear energy
chemical to mechanical.
tthe measure of the average kinetic energy is?
tempeture.
What are the 3 rules of kinetic theory?
When molecules collide with each other, no energy is gained or lost. The space occupied by the molecules of gas in a container is very negligible. These molecules always have linear motion.
Is metal a good heat shield?
it can be an excellent heat shield.
when producing electricity you need to spin what?
terbine
what is the formula for chemical to mecanical?
KE+ME
what are the three forms of heat transfer?
conduction, radiation, and convection.
what is the main idea of kinetic theory?
particles of matter are in constant motion.
When hang-drying clothes, which is faster, indoors or outdoors?
clothes will dry the fastest when hung up outdoors.
wind and hydro electric use a what resource.
renewable
what happens to a rollercoasters potential energy as the rollercoaster goes down a hill?
converts into kinetic energy
grabing a hot handle of a pan is an example of?
conduction
What happens if the kinetic energy of a gas is lowered?
the temperature of the gas will also decrease.
When I sit by a campfire, how does its hot air heat me?
thermal radiation.
which from of energy production causes acid rain?
coal
what law says energy can not be created or destoryed?
the law of conservation of energy
energy always moves from?
the substance with the higher temperature to the substance at lower temperature
Which phase of matter has the lowest kinetic energy?
Solids
Do humans give off radiation?
Yes, all objects, including human bodies, emit electromagnetic radiation.
