Examples "there was an atmosphere of excitement" Used in print (William G. Pollard, Physicist and Christian....)The conversation of the characters creates an atmosphere suggesting the usual mixture of pleasures , foibles , irritations , and concerns which would characterize the common life of a normal village in any age .

Gardiner, S.J., Movies,...)Motion-picture exhibitions took_place in stores in a general atmosphere like that of the penny_arcade which can still be found in such urban_areas as Times_Square .

[ noun ] (physics) a unit of pressure: the pressure that will support a column of mercury 760 mm high at sea level and 0 degrees centigrade
Synonyms Used in print (Raymond C. Binder et al., editors, Proceedings...)In free_burning electric arcs , for_instance , approximately 90 % of the total arc power is transferred to the anode giving_rise to local heat fluxes in excess of **f as measured by the authors - the exact value depending_on the arc atmosphere . (Harry H. Hull, "The Normal Forces and Their Ther...)By this method it was determined that the normal pressure exerted by a sample of polybutene ( molecular_weight reported to be 770 ) was over half an atmosphere . (Francis J. Johnston and John E. Willard, "The...)Both types of tube withstood the pressure of approximately 20 atmospheres exerted by the carbon_tetrachloride at 220 ` . Sets of reaction tubes containing 0.2 of an atmosphere of added oxygen in one case and added moisture in another , both gave reaction rates in the range of 0.1 to 0.4 of the chlorine exchanged per hour . When typical reaction cells to which 0.3 of an atmosphere of oxygen had been added were illuminated , chlorine and phosgene were produced . Related terms |

[ noun ] the mass of air surrounding the Earth
Synonyms Examples "there was great heat as the comet entered the atmosphere" "it was exposed to the air" Used in print ("Editorials"...)These gentlemen are calling_for a resumption of testing - in the atmosphere - on the greatest possible scale , all in_the_name_of national security . (James A. Ibers et al., "Proton magnetic resonance...)However , **f adsorbs water from the atmosphere and this may account_for the low chromium analysis and high total weight loss . One sample , which had been exposed to the atmosphere after evacuation at 375 ` C , showed the presence of adsorbed water ( about 0.3 wt % ) as evidenced by a weak resonance line which was very narrow at room_temperature and which disappeared , due_to broadening , at low_temperature . (J. F. Vedder, "Micrometeorites", in Francis S. J...)De_Jager ( 1955 ) has calculated the times required for these particles to reach the atmosphere under the influence of the Poynting-Robertson effect , which in this case causes the orbits to become more_and_more eccentric without changing the semi major_axis . The figures in the next-to-last column are derived with the assumption of 50 per_cent shielding by the Earth ; hence , these figures apply immediately above the Earth 's atmosphere . Related terms |

[ noun ] (meteorology) the weather or climate at some place
Synonyms Examples "the atmosphere was thick with fog" Used in print (Raymond C. Binder et al., editors, Proceedings...)Inflow of air from the surrounding atmosphere was prevented by the two disks shown in figure 2 . (Frieda Arkin, "The Light of the Sea," in The...)She turned and walked stiffly into the parlor to the dainty legged escritoire , warped and cracked now from fifty years in an atmosphere of sea_spray .

[ noun ] the envelope of gases surrounding any celestial body
Used in print (Cornell H. Mayer, "Radio Emission of the Moon...)It has recently become practical to use the radio_emission of the moon and planets as a new source of information about these bodies and their atmospheres . Observations of the radio_emission of a planet which has an extensive atmosphere will probe the atmosphere to_a_greater_extent than those using shorter wave_lengths and should in some cases give otherwise unobtainable information about the characteristics of the solid surface . Observations of the radio_emission of a planet which has an extensive atmosphere will probe the atmosphere to_a_greater_extent than those using shorter wave_lengths and should in some cases give otherwise unobtainable information about the characteristics of the solid surface . For the case of Jupiter , the radio_emission spectrum is definitely not like the spectrum of a black-body radiator , and it seems very likely that the radiation reaching the earth is a combination of thermal radiation from the atmosphere and non thermal components .
