all atoms have thermal heat energy because the atoms or molecules that make matter are in constant motion
the energy that flows due to temperature differences;always transferred from warmer to cooler substances
heat transfer by the movement of mass from one place to another;can take place only in liquids and gases
moves about the planet heat gained by conduction and radiation from the sun;heating of the Earth isn't even
the transfer of heat by the actual movement of warmed energy in a gas or liquid by movement of currents. (It can also happen in some solids, like sand)
electromagnetic waves that directly transport energy through space;sunlight is a form of this that brings heat to our planet without the aid of anything
clouds form a blanket which keeps the heat from escaping back into the atmosphere. The heat stays in keeping us warmer.
why do different metals conduct heat different rates
different materials have different conductivites
movement of matter due to differences in density that are caused by temp. variations can result in transfer of energy as heat
energy that is transferred as electromagnetic waves, such as visible light and infrared waves
What makes a substance a good or poor conductor depends in part on
how much energy is required to change the temperature of the substance by certain amount
Specific heat of any substance is the amount of energy required to raise the temperature of
1 kg of that substance by 1K
