损耗的能量而沸腾的酒精水加热,然后计算每个试验总结。从2试验估计酒精灯是26.61 KJ的能量形式,因此它可能是大约10 – 15小径将吸收整个酒精能源沸腾的水。结果表明,酒精能量超过了沸腾的水在这个实验中所需的能量。这也是清楚的从上面的图,随着温度的增加能源热能迅速增加,但在某种程度上的时间减少了,因为当水开始沸腾。烧杯的结果表明,增加大小的平均温度降低,因此需要更多时间沸腾的水比减少大小烧杯。这表明烧杯也从酒精火焰在沸腾的水吸收的能量。这意味着某些部分的能量也在空气对流,所以100%的能量没有被吸收的水(•哈斯r . 1971)。在这种情况下,法律求和应用持续的高温,但对假说。这个实验可以改进或增强的结果可以通过做实验在没有空气的真空,在空气和能量的烧杯。能量然后从酒精火焰,只会被转移到水沸腾的时间可能会比预期的降低。在这个实验中比热是常数和质量,可以做这个实验正是当时如果质量可以计算(Kazakov,安德烈。2008 . .这将给更精确的结果,因为质量是随时间。总而言之,这个实验是生的,可以进一步提高与照顾环境,校准,使用一些软件分析因为帮助下的软件数量的线性方程可以很容易地开发试验。
新加坡管理大学论文代写：改善环境试验
The energy dissipated while heating the alcohol for boiling the water is calculated and then the each trial is summed up. From the 2 trials it is estimated that the energy form the alcohol lamp is 26.61 KJ, therefore it may be around 10-15 trails which will absorb the entire alcohol energy for boiling the water. The results show that alcohol has more energy than the energy needed for boiling the water in this experiment. This is also clear from the above graph that with increase in temperature the energy heat energy increased rapidly but at some point of time it reduces because that is the time when the water starts boiling. The obtained results shows that with the increase in beaker size the average temperature decreases and therefore it takes more time for boiling the water than with the decrease size beaker. This indicates that the beaker also absorbs the energy from alcohol flame before boiling the water. This means that some part of the energy is also going in to air through convection and so the 100% energy is not being absorbed by the water (Haase, R. 1971). In this case the law of constant heat summation applies but against the hypothesis. This experiment can be improved or the enhanced results can be obtained through making the experiment in vacuum where there is no air, and the energy is going in to air with help of beaker. The energy then will only be transferred to water from alcohol flame and the boiling time might reduce than expected. In this experiment the specific heat is taken constant and also the mass, this experiment can be done precisely if the mass at the time can be calculated (Kazakov, Andrei 2008.. That will give the more precise results because the mass is decreasing with the time. Overall, this experiment is raw, and can be improved further with taking care of the environment, calibration, and using some software analysis because with help of software the linear equations can be developed easily for number of trials.
