Introduction In this experiment‚ we will be figuring out how much does 80 degree celsius water reduce in temperature in 15 minutes‚ using different materials to insulate the heat. The five materials that will be tested are: Aluminium foil‚ plastic wrap‚ newspaper‚ felt‚ and bubble wrap. Aluminium foil is a reflective material; this means that it bounces the thermal energy back to the foiled object. It also absorbs the heat. Not only does it stop heat loss‚ but Aluminium foil is also useful for

Investigating the effects of changing temperature on the activity of enzymes Background information: Renin is an enzyme that catalyses the coagulation of milk. It is found in the stomach of many animals and is used in making cheeses and junkets. It is found in the gastric juices or gastric mucosa of many mammals‚ including humans. In the human stomach‚ particularly those of infants‚ rennin works to curdle milk so that pepsin‚ another stomach enzyme‚ can further breakdown the proteins into absorbable

4. Which city has the warmest annual temperature? The city of Vancouver has the warmest annual temperature. This is because of the Ocean currents together with the Wind and Air masses‚ and Vancouver’s Nearness to water. Latitude: Even though Vancouver is fairly south‚ it isn’t as southerly as many other places making latitude‚ not a cause. Ocean Currents: Ocean currents play a huge role in the average annual temperature of Vancouver. The Warm North Pacific current brings warm water towards Vancouver

Experiment 16: Heat conduction Introduction In this laboratory you will study heat flow across a temperature gradient. By comparing the temperature difference across one material to the temperature difference across a second material of known thermal conductivity‚ when both are conducting heat at a steady rate‚ you will be able to calculate the thermal conductivity of the first material. You will then compare the experimental value of the calculated thermal conductivity to the known value for that

The Effect of Varying Temperatures to the Rate of Respiration of Bufo marinus Statement of the problem: At which environmental temperature‚ do toads have the highest respiration rate? Most animals obtain oxygen‚ which comprise 21% of the air‚ from the environment. Oxygen combines with hemoglobin of the blood to form oxyhemoglobin. Oxyhemoglobin is transported to the tissues where oxygen is released and used for the metabolic functions of the animal. The functions produce waste materials‚ such

The effects of environmental temperature on respiration rates of mice were observed in this experiment. I hypothesized that when environmental temperature decreased‚ the respiration rate of mice would increase. I predicted that if environmental temperature decreased‚ the respiration rate of mice would increase. The respiration rate of the endotherm was measured using the Qubit/Vernier system and the S152 CO2 gas sensor‚ a device that measured the CO2 concentration in the air. The independent variable

spectrum of sunlight yields the highest temperature? My hypothesis is that the blue/violet part will have the highest temperature. The blue/violet part has the highest frequency out of all the colors on the visible light spectrum and it also has the highest amount of energy. Therefore‚ I hypothesize that it will have to the highest temperature as well. After conducting the experiment‚ I noticed that during the duration of five minutes‚ the temperatures of all four thermometers increased. The

The goal of this experiment was to explore how temperature would influence the rate of cellular respiration of beans. It was hypothesized that as the temperature of the beans increased‚ the rate of cellular respiration would increase as well. In this experiment‚ the independent variable was the temperature‚ which gradually increased as time went by‚ and the dependent variable was the rate of cellular respiration‚ which was shown by the change in the amount of CO2 and O2 in the container. During the
