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

1.0 Introduction 2.1 History Do you know that ice was once used to hold a burning candle during the Qing Dynasty back in 1644? The ice lantern was first created in the northeast China during the winter time. It was said that‚ back in the 17th century‚ ice lanterns were made by fisherman and farmers in the northeast China to prevent the candle from being blown out by the strong wind. Due to the climax weather in northeast China‚ ice can easily be formed by just letting a bucket of water to

Assignment: Chronicles of Ice Summary: In Chronicles of Ice‚ Gretel Ehrlich sets out to “learn whatever lessons a glacier has to teach”‚ and to share what she has learned with us‚ as readers. The lesson the author relays to us is that the fate of the glacier is inextricably linked to that of the biological health of the Earth itself. Ehrlich uses the glacier as a device to show both cause and effect of the declining health of the Earth’s climate. The gases and particulate trapped in the ice provide the historical

Thinking fast on your feet‚ and being the the smart chemistry student you are‚ you and your friends go buy oil‚ water and dry ice. With these materials you are able to make a contraption to help blow the balloons up at a fast rate. Considering the time that it takes for the balloons to blow up and the capacity they can hold‚ you were able to calculate the time in which it took

Salt and Ice; Minnesotas Battle Abstract Salt is applied in the thousands of tons every year to reduce ice and‚ in turn‚ reduce accidents on Minnesota roads. When the ice and snow melt each spring‚ the majority of this solution is relieved into rivers and lakes through storm drains on Minnesota roads. The salt negatively affects fish and aquatic plants by dehydrating them and altering fertilization. The damaging effects of sodium chloride are long term and not easily repaired. The Minnesota

Lye is a corrosive alkaline substance‚ commonly sodium hydroxide (NaOH‚ also known as ’caustic soda’) or historically potassium hydroxide (KOH‚ from hydrated potash). Previously‚ lye was among the many different alkalis leached from hardwood ashes.[1] Today lye is commercially manufactured using a membrane cell method. Solid dry lye is commonly available as flakes‚ pellets‚ microbeads‚ and coarse powder. It is also available as solution‚ often dissolved in water. Lye is valued for its use in food

no right or wrong meaning. Poetry speaks to each of its readers differently. In Robert Frost’s poem “Fire and Ice‚” it is both a lyric and didactic poem. There are several meanings that can be argued in “Fire and Ice.” Is Frost’s “Fire and Ice” about the world ending or a past love that has ended? In the first two lines‚ Frost writes‚ “Some say the world will end in fire‚ / Some say in ice.” The first thought that comes to mind when reading these two lines is that the poem is about the debate on

In the early 1990s the ice cream industry was state regulated. It had artificial market‚ where all production was sold despite huge overproduction in the industry. During transition from state governed to market economy‚ the industry shrank rapidly and was unattractive mainly because of political and financial turmoil. Once Russian economy reemerged from the crisis‚ in the late 2001‚ the industry stabilized. Industry forces started to play major part in its attractiveness and macro factors did not

Melting Ice * Salt is routinely used to make icy roads and sidewalks safe in the winter. As soon as the salt comes in contact with the ice‚ the surface of the ice starts to melt. This only works‚ however‚ if the temperature outside is at or near freezing. If it is too cold outside‚ the ice itself becomes very dry and salt is not as effective in melting it. Salt Reduces Freezing Temperature of Water * Salt works by lowering the freezing temperature of water. Salt water needs to reach a colder
