Question	Answer
the temperature of a gass is proportional to the	average kenetic energy of the gas molecules
the kinectic molecular theory explains the expansion of a solid material with increases of temperature as basically the result of	molecules moving a little farther apart
two degree intervals on the celsius temperature scale are	equivalent to 3.6 farenheit degree intervals
a temperature reading of 2*c is	equivalent to 35.6*F
the temperature known as room temperature is nearest to	20*c
using the absolute temperature scale, the freezing point of water is correctly written as	273 K
the metric unit of heat called a calorie is	all of the above (specific heat of water, energy needed to increase the temp of 1 gram of water 1 degree celsius, equivalent to a little over 4 joules of mechanical work)
which of the following is a shorthand way of stating that the temperature change of a substance is directly proportional to the quantity of heat added	Q 8 delta T
the quantity known as specific heat is	the energy needed to increase the temp of 1 gram of a substance 1 degree celsius
if 1 kg of soil and 1kg of water each recieve 1 kcal of energy, ideally	the soil will be 5*c warmer than the water
the heat transfer that takes place by energy moving directly from molecule to molecule is called	conduction
the heat transfer that does not require matter is	radiation
styrofoam is a good insulating material because	it contains many tiny pockets of air
the transfer of heat that takes place because of density difference in fluids is	convection
when a solid, liquid, or a gas changes from one physical state to another, the change is called,	a phase change
latent heat is "hidden" because it	goes into or comes out of internal potential energy
as a solid undergoes a phase change to a liquid state, it	absorbs heat while remaining at a constant temperature
the condensation of water vapor actually	warms the surroundings
water molecules move back and forth between the liquid and the gaseous state	at all times with evaportaion, condensation, and saturation defined by the net movement
no water vapor is added to or removed from a sample of air that is cooling, so the relative humidity of this sample of air will	be higher
compared to cooler air, warm air can hold	more water vapor
a heat engine is designed to	convert heart into mechanicla energy
the work that a heat engine is able to accomplish is ideally the equivalent to the	difference in the heat supplied and the heat rejected
