Temperature and Heat

electrons bump into atoms and other electrons

Heat transfer occurs when

the temperature difference between an object and its surroundings

Newtons law of cooling says that the rate of cooling depends on

a good emitter of radiation

a good absorber of radiation is

a poor absorber of radiation

a good reflection of radiation is

metals, in general, are good heat conductors

a piece of metal will feel colder than a piece of wood at the same temperature, why?

the bar keeps the paper relatively cool

a piece of paper wrapped around a thick metal bar will not ignite when touched with a lit match because

warm air over the shore rises and and cooler air from the ocean takes its place

at night, a sea breeze results when

water expands when it freezes

during a very cold winter, water pipes sometimes burst, this reason for this is

fluids

energy transfer by convection is primarily restricted to

wood's poor conductivity

firewalkers who walk barefoot on red hot wooden coals depends on

terrestrial radiation

global warming by greenhouse effect mostly results from the fact that an atmosphere with excess carbon dioxide is less transparent to

radiation

heat travels from the sun to the earth by

lower than its surroundings

if a poor absorber of radiation were a good emitter, its temperature could remain

less likely to freeze

if the specific heat capacity of water were higher than it is, lakes would be

cools

if volume of air is warmed, it expands, if a volume of air expands, it

high frequency light in and preventing low frequency radiation from escaping

in a florist's greenhouse, glass acts as a one way, letting

radiant energy

infrared radiation is a form of

total amount of energy contained in an object

internal energy is the

absorber

plastic foam is a good heat

long wave length radiation is absorbed by the atmosphere

radiation from the sun often gets trapped in Earth's atmosphere, the reason for that is

land is hotter than water, cool air above the ocean flows downward, a high pressure area is created high above the water, a low pressure area is created just over the shore

sea breezes are usually from the sea towards the land during the day because

a high specific heat capacity

some molecules are able to absorb large amounts of energy in the form of internal vibrations and rotations, materials are composed of such molecules would have

average molecular kinetic energy in a substance

temperature is related mostly to the

absorbtion of terrestrial radiation

the lower atmosphere is directly warmed by

water has the highest specific heat capacity

the reason an ocean's temperature doesn't vary much from one season to another is that

they reflect a lot of energy

the reason light colored clothes help keep you cool in warm weather is because

air convects heat well, hot air rises, air is a poor heat conductor, hot air convection currents travel upwards

the reason your finger doesn't get burned when held next to a candle flame

larger

when an iron ring is heated, the hole becomes

the boiling water

which cools faster, a pot of boiling water left at room temperature or a pot of luke warm water at the same size left at room temperature

water

which has a higher specific heat capacity, water or sand?

the water

which is denser, ice at zero degrees C or water at four degrees C
