63解析：本题考查理想气体的状态方程。加热前，封闭气体的压解析：本题考查理想气体状态方程和热力学第一定律。气体pa=1.0×105Pa、温度T。=1a十273K=300K,体积V1=V一体积缓慢减小，压缩气体的过程中，外界对球内气体做正功，A项V。=1.6×10m3,打开铁炉前的瞬间，封闭气体的温度T=t十错误：根据玻意耳定律，有pV=C,可知V减小时，球内气体的压273K=540K,水蒸气占混合气体体积的25%，则有V2=(1强p增大，B项正确：因为温度不变，所以球内气体的内能△U=0,25%)V,=1.2×102m3,设打开铁炉前的瞬间，混合气体的压强外界对球内气体做功，根据热力学第一定律，有△U=Q十W,可知球内气体向外界放热，C项错误：球内气体的温度不变，则球内气体为p,则有P-P,解得力=2.4X10Pa,B项正确分子热运动的平均动能不变，D项错误。答案：B答案：B
