How does lava temperature impact viscosity and velocity? The higher the temperature the lower the viscosity which allows it to develop a smooth surface skin‚ but this is quickly broken up by flow of molten lava‚ it creates a rough‚ clinkery surface. The lower the temperature of the magma the higher the viscosity which allows the lava to travel down the slope. In the group the average velocity was 0.91 cm/s . How the “lava” flowed was in a high viscosity and a low velocity because the “lava” was

point the heat will denature the enzyme as it reaches too high of heat. If an enzyme has been denatured it means the shape has been altered therefore cannot perform its function‚ many factors can cause this including high heat. The hypothesis is if temperature is increased the amount of activity rate will increase. The results for the rate of oxygen production (dependent variable) will increase as the heat increases. The reason is a chemical reaction to the heat gives it energy. Enzyme reactions are important

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

Ocean Acidification SDI: Solubility of CO2 in different temperatures Aim: To observe the solubility of CO2 in different temperatures Hypothesis: We hypothesise that in cold water the level of co2 absorption will be greater than warm water which will mean the air space in the cylinder will be less compared to warm water. Independent: Type of water. Dependant: room temperature‚ amount of water‚ type‚ size and amount of tablet‚ amount of water in the basin. Materials: 250ml graduated

GREENHOUSE EFFECTS IntroductionThe greenhouse effect is a process by which thermal radiation from a planetary surface is absorbed by atmospheric greenhouse gases‚ and is re-radiated in all directions. Since part of this re-radiation is back towards the surface and the lower atmosphere‚ it results in an elevation of the average surface temperature above what it would be in the absence of the gases.[1][2] Solar radiation at the frequencies of visible light largely passes through the atmosphere to

Discussion The data demonstrates that there is a larger temperature change in the cheese and bacon balls compared to the popcorn. This temperature change of the water is due to the cheeseball having more energy due to its fats and sugars‚ therefore releasing more heat and differing the temperature more than the popcorn with the less fat and sugar. The mass of the food was consistent throughout the experiment ranging from 2.98 - 3.25‚ therefore the mass of food combusted was consistent as well. The

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

If the earth was at an axial tilt of 0° there would be absolutely no seasonal change‚ the temperature would remain even at all times of the year. The temperature around the equator (0°latitude) would be about 40°C or 104°F‚ and the 80°N latitude would be at about -35°C or -31°F; with the temperatures remaining this way all year round and no seasonality migration and aggregation of the poles would be mythical; also would be too cold for reproduction hence no “annual flush of productivity.” In the

Variable was the heat lamp‚ and the dependent variable was the temperature of the soil‚ because the temperature varied based on whether the heat lamp was turned off or on‚ and whether there was extra water added or not. Our hypothesis was proven correct‚ because the dry soil’s temperature was hotter than the damp soil’s temperature when the heat lamp was on‚ but then it decreased when it turned off‚ while the damp soil’s temperature remained the same. This is because dry soil contains little moisture

Alcohol and its Effects Rachael Wade Ivy Tech Community College Alcohol and its Effects Alcohol can be a very harmful substance. Alcohol can be abused‚ and people can get addicted to it like any other drug. It can impair coordination and judgment as well as a lot of other things. Alcohol can also have long term effects on the organs in the body. It can affect people psychologically as well as behaviorally. Many deaths that occur each day are caused by alcohol. Consuming alcohol affects a
