Next I will pour the Zinc into the test tube containing CuSO4. 3.Finally I will measure the final temperature using a thermometer and record the temperature rise in °c. (I will carry out all my experiments under lab safety precautions.) Variables *I will vary the mass of Zinc‚ & use the following Zinc weights:

The earth doesn’t have an even balance of heat and the reason for this is because the earth is a geoid ‚ the sun’s rays hit directly on the equator(caused by unequal insolation due to three factors: angle of strike‚ atmospheric depletion and surface area.) and then move outwards towards the polar areas. The atmosphere together with the ocean currents work hard to try and even out the imbalance of heat energy by redistributing the air from the equator to the Polar Regions but also from the Earth’s

1.The average temperature contrast between winter and summer is greater for continental polar air than for maritime tropical air. Explain why. Maritime tropical air is very warm and humid because its source regions are tropical and subtropical seas. This air mass retains these properties year-round and is responsible for oppressive summer heat and humidity east of the Rocky Mountains. Dry continental polar air develops over the northern interior of North America. In winter‚ continental polar air

conducted to determine the optimal temperature for bacterial and fungal Amylases and evaluate how temperature affects the catabolic rate of enzymes. Enzyme reaction rate was measured using an Iodine test in which drops of starch solution with either fungal or bacterial Amylase exposed to different temperatures were mixed with Iodine. Iodine is a dark blue color in the presence of starch and turns light yellow in its absence. Bacterial Amylase had an optimal temperature of 55°C‚ meaning that starch was

How Does Temperature affect the Ability to Bounce of a Ping-Pong ball? Physics Design Practical Research Question How is the bounce-height of a ping pong ball affected by it’s temperature? This research questions aims to find out how the temperature of a ping pong ball affects the vertical height bounce‚ after being dropped from 1 metre. I will be measuring the bounce height using a video camera to find the heightest point. I will use the top of the ball for ease of results. Hypothesis:

High Temperature Insulation Market - HTI Application and Temperature Range - Global Trends & Forecasts (2011 - 2016) On 1st May 2012 The increasing cost of power and the rapid depletion of conventional sources of energy have necessitated effective heat management and energy conservation in industrial processes. High temperature insulation (HTI) products provide high compressive strength and low shrinkage at high temperatures; and thus offer a cost-effective energy management solution for industrial

with a larger density will increase the temperature of the ice faster than salts with a smaller density because the heavier salts will sink through the ice faster since they have a heavier density than water and stop the molecules from staying ice faster‚ consequently raising the temperature of the solution‚ than lower density salts would. . The data I collected shows potassium chloride‚ which has a density of 1.98 g/㎤‚ increased the solution’s temperature at a faster rate than any of the other solutions

effects of catalase under varying controlled conditions. The scope of this experiment includes Metabolic processes‚ such as cellular respiration‚ and it poisonous byproduct hydrogen peroxide. The methodology includes procedures; multiple variables were tested in specific concentrations; that test the reaction rates of the enzyme catalase over a fixed period of time. The major conclusion was that catalase reacts faster in warm temperatures that are neither freezing nor boiling‚ catalase performs well
