科学小实验：温度与气压.doc

科学小实验：温度与气压辛国秦原理 在密闭容器内，气压与温度变化正相关。即气压随着温度的升降而升降。实验设计 1.实验装置 锥形瓶1只，胶塞1个，上打2孔：分别接压强、温度传感器探头。（见照片）2.计算机，朗威DISLabV6.8采集器及通用软件，压强传感器、温度传感器各1个。3.大烧杯，热水，冰袋。实验步骤 1.连接温度、压强传感器及采集器、计算机，测得瓶内温度、气压的初始值并记录。2.将冰袋置于打烧杯内，再把实验装置放在冰袋上。测试降温过程中瓶内的气压数据并记录。3.除去冰袋，向大烧杯倒入热水，把实验装置放入烧杯水浴。测试升温过程中瓶内气压数据并记录。附一：实验即时图片 起始温度、压强低温与气压高温与压强结论1气压随着温度的升降而升降。2附照片实验装置 连接传感器、采集器、计算机 冰袋低温测试 热水高温测试附即时数据记录表计算表格P1T2t191.127.80291.127.8539127.710490.927.715590.927.620690.827.625790.927.530890.827.435990.727.4401090.325.6451190.225.6501290.325.5551390.225.5601490.325.4651590.225.3701690.225.3751790.225.2801890.225.2851990.225.1902090.225.1952190.2251002290.124.91052390.224.91102490.224.81152590.124.71202690.224.71252790.224.71302890.224.61352990.224.61403090.124.51453190.224.51503290.124.41553390.124.41603490.224.31653590.124.31703690.124.21753790.224.11803890.224.11853990.2241904090.2241954190.223.92004290.123.92054390.123.82104490.223.82154590.223.72204690.223.72254790.223.72304890.223.62354990.123.62405090.123.52455190.223.52505290.223.52555390.123.42605490.123.42655590.223.32705690.223.32755790.123.22805890.123.22855990.123.12906090.123.12956190.223.13006290.1233056390.2233106490.1233156590.222.93206690.122.93256790.122.93306890.222.83356990.222.83407090.122.83457190.222.73507290.222.73557390.222.73607490.122.63657590.122.63707690.222.63757790.222.63807890.222.53857990.122.53908090.222.43958190.222.44008290.222.44058390.222.34108490.222.34158590.222.34208690.222.34258790.222.24308890.222.24358990.222.24409090.322.24459190.222.14509290.222.14559390.222.14609490.2224659590.3224709690.2224759790.3224809890.321.94859990.221.949010090.221.9495101106.9490102106.949.15103106.949.210104106.949.315105106.949.420106106.949.425107106.949.530108106.849.535109106.949.640110106.849.645111106.849.750112106.749.755113106.749.760114106.749.765115106.549.870116106.549.875117106.549.880118106.449.885119106.449.890120106.449.895121106.449.7100122106.449.7105123106.349.7110124106.349.7115125106.349.7120126106.349.7125127106.149.6130128106.149.6135129106
