Words • 1318
Pages • 6
  The Mpemba Effect is a phenomenon in which hot H2O freezes faster than cold H2O. This phenomenon was discovered in Tanzania, Africa, by a high school pupil named Mpemba. ( Kurtus ) Conduction, convection, radiation, and vaporization are methods through which heat can be transferred from one substance to another and are necessary in understanding the Mpemba Effect. When an object or liquid is at a different temperature than its milieus, heat transportation occurs so that all the organic…...

Bio lab report on insulators

Pages • 6
Foam is 5 percent air so the air molecules slow down the heat transfer from the liquid, so it stays warmer longer than cotton insulation. This leads me to predict that foam would be the best insulator, as it would trap the heat more, which will cause deficient heat lost. Identification of Variables There are three variables I will take in consideration whilst carrying out my investigation. The independent variable will be the types of materials used for insulation, which…...

Uncertainty in measuring time was ±0. 01s according to the stopwatch but while measuring mass you have to first look at the time in stopwatch and then the mass in the electronic balance and because humans cannot react instantly it is estimated to be ±1s. Uncertainty in measuring mass of the water was ±0. 1g because it was measured using a weighing machine with the ±0. 1g uncertainty. The graph of mass of water evaporated over time is linear because…...

To investigate different materials for the most effective thermal insulator for a house. Introduction Heat transfer is the gain and loss of energy. There are three ways in which thermal energy can be transferred:  Conduction  Convection  Radiation Conduction - this is when energy travels from molecule to another. When one molecule receives energy it begins to vibrate and hits other molecules and makes them vibrate. And will spread throughout the object. Convection - this will only occur in gases and…...
