空气比热容温度对照表

空气比热容温度对照比热容是指没有相变化和化学变化时，一定量均相物质温度升高1K所需的热量。利用比热容的概念可以类推出表示1mol物质升高1K所需的热量的摩尔热容。与比热相关的热量计算公式：Q=cmAT，即Q吸（放）=cm（T初-T末），其中c为比热，m为质量，Q为能量热量。吸热时为Q=cmAT升（用实际升高温度减物体初温），放热时为Q=cmAT降（用实际初温减降后温度）。或者Q=cmAT=cm（T末-T初），Q>0时为吸热，Q<0时为放热。比热容的计算公式一般为：二QC~Q吸=cm（t-to）Q放=cm（to-t）c表示比热容m表示物体的质量to表示物体的初温t表示物体的末温注释：【1atm=1标准大气压=1.01xiO5Pa1atm=760mmHg=1.01325X105paM0.1Mpa=1Kgf/cm2】空气的比热容没有确定值，即便是在温度确定时，通常使用定压比热容或定容比热容来反映空气比热容的大小，这两者都与温度有关（温差不太大时可认为基本相等）。一定质量的物质，在温度升高时，所吸收的热量与该物质的质量和升高的温度乘积之比，称做这种物质的比热容（比热），用符号c表示。其国际单位制中的单位是焦耳每千克开尔文［J/(kgK)］或焦耳每千克每摄氏度［J/(kg•可。J是指焦耳，K是指热力学温标，即令1千克的物质的温度上升(或下降)1开尔文所需的能量。F面是空气比热容温度对照表:(工程常用物质的热物理性质手册〉表m宇气在不同JK力和温再FTJE诀容110OlauL］：ii«j-dm|0iL^70minI(X)mTilIj/Cv-2E1.1514B48冏曲，r1.4Q317C7!14B2X卫--1^.140191.«17-273.1E100-17：!.151.4016110'1631⑹51.42Q21,4&6D1.603517672120-153,1.40151.41G61.47301.55131J639511I.4Q131.41391.43781S391.57401：0-1^1,44151.41191.44731.49C11.5350-273.15150-111.41021.43331.«T34150842.7372160-itaL馬1.4414i^on1,43汕1.4614t.489B2.1H£I.'?-10工151.4*141.«791.42401.4521t.47561.M8C17-93.151.«14L«?11.42531.4443t.1648176782.3139J90-<..■1j4M31.40M1.斗2221.4391L4bt>0-273.1E卿-73.151.44121.4C571.41971.4M3L44891.U1S1.9MH2.1376210T：.…，1.40131A0S31.41T71.43CC1-44371.C02E5.SD3S1.M02220-S3.1S1.4412：.4C4«1.415B1.4272t.4S891.574C173181.9769230-灶!5V40111,3441.41431.42461.4S431.M15i.eais1.Q012240-33.151.4*1114123k4i22t.43131.53341.693417439-273.15250-23.15k«0914-I1B1.42011.42B41.51B54.29€61.6990260-IX151.4D0a1^0321X1071.41B31.42S91.50621.59&51.6«31Z7U-J.W1.44291.4酣丁Mt血仁41331.4S5E1辭甜2SO6.R5V4D041.4A24140B71.415G1.42141.S511伽瓯29016.S5140021.40201407S1.41S51.41941.47B£1.53651.5G87理30026.S51.40001.44)171.40701.41231.41771.47171.52401.57113)036.B51.3397140131.40621.41111.41611.4C581.51321.5553320Ifi.B51399314008140531,41001.41461.46031.5Q351.5425!33056.851.3990140D414G451L40894.41311.45531.4^1.5307!340nh8--1.3986139991.4G3Bt.407T141181.4507143711.5202-273.153501.390^1.3^931.4030□241.44fi51.4Q041-S109360->1-357613&B71.40221.40561.409T1.442S147421.502437096V1.3*10139311.40141.40461.4079143941.4BB51.49473旳俪用139641.397514Q051,4036J,40661,4361-J.40321.4B7339011民13$5S1.39S813957140Z51.40541432S1.45B31.4B13^273.“JW..126.851.39521.3&611.39871.4114140411.42991,45371.47521IQ—13G.8513945TR5313那1-4Q041.40?&TQ：14492V4m420】城1.39371.3M61.397Q1.3*M140161.4246144491.463043QL5&诙1.39301.39381阳旳1.39B2140031.42201,4412145BS110叽139?^1.J929139S013^7?1仲11.41M1.43791WT-273.15150L76.851.39131.39201.3M01.3*60f.39791.41U1.4342160186.851.39021.39111.391.39491.39671.414E1.43121.4461
