Have you ever seen dry ice‚ well let me show you. To measure the evaporation rate it is important to know that a half pound of dry ice will be placed outside and timed. The same thing will happen but in a cool room. If the dry ice is -109.3°F then it will evaporate in any condition warmer. The hypotheses is that the dry ice in the outside will evaporation faster. It is important to understand this because if you are trying to store dry ice and you put it in a freezer it will still evaporate. So in

Ailine Veiga Question: what is the heat of fusion of ice? Hypothesis: To get the heat of fusion of ice we need to determine the Energy it takes to melt the ice and also the mass of the ice and determine the heat of fusion. To determine the mass of the ice melted (m) we start by determine the volume of the water generated when the ice melted. This is the difference between the final volume (v2) and the initial volume (v1). Using the density of water (1.0g/mL)‚ this volume can be converted into mass

The problem of the ice melting The melting of polar ice is primarily caused by the increasing amount of gas emissions‚ mainly CO2 rising into the atmosphere (global warming) Global warming is the rise in the average temperature of Earth ’s atmosphere and oceans. Since the early 20th century‚ Earth ’s mean surface temperature has increased by about 0.8 °C. Scientists are more than 90% sure that it is caused by rising amount of concentrations of greenhouse gases‚ which are produced by human activities

The Little Ice Age started from 1300 to 1850. During this time‚ Europe and North America have subjected too much colder temperature when comparing to the 20th century. Since 1250 A.D‚ temperatures started dropping. Then‚ from 1600 to 1700‚ this was the coldest period in little Ice Age. After that‚ in 1850‚ the temperatures started warming again. There were two different states in this period. The first state was in 1300’s to 1500’s and the climate was warmer. The second state was about 1600’s to
