Abstract This experiment was designed to answer the question does temperature affect the amount of osmosis? The hypothesis predicted was that the higher the temperature the more osmosis would occur‚ but too high the osmosis would halt due to enzyme and substrate overheating and losing shape. After research and class time it was concluded that osmosis is a passive transport and would not require energy or enzymes due to it going from high to low concentrations with the gradient

atmospheric pressure is suspended from the ceiling of a large room. The steam temperature entering the pipe is 120 oC‚ and the air temperature is 20 oC. The overall heat transfer coefficient on the outer surface of the covered pipe is 10 W/m2.K. if the velocity of the steam is 10 m/s‚ at what point along the pipe will the steam begin condensing and what distance will be required for the steam to reach a mean temperature of 100 oC? Question 2: Consider a horizontal‚ thin walled circular tube

2. How is the colour related to surface temperature of the star? The correlation between the surface temperature of a star and its colour is due to the phenomena known as black body radiation .A star is a black body‚where it aborbs all the radiation falling upon it.AS its temperatures gets hotter thanits surrounding‚the star radiates its on electromagnetic radiation‚known as black body radiation. This radiation is distributed unevenly but contionously through multiple wavelengths of the electromagnetic

thermoregulation Prior Knowledge Questions (Do these BEFORE using the Gizmo.) Homeostasis is the ability to maintain a stable environment inside the body. For example‚ your body does things to maintain constant blood sugar levels and body temperature. 1. What are some things you do to stay cool on a hot day? Some things I do to stay cool is to drink water‚ wear less clothes and turn the fan/ air conditioner on at the location I am at. 2. What can you do to warm up on a cold day? On a cold

Can tegu lizards maintain an elevated body temperature during their reproductive season? Experiment: Dr. Glenn Tattersall and a team of researchers in Rio Claro‚ Brazil studied changes in the heart rate and body temperature of tegu lizards (Salvator merianae)‚ by implanting lizards bred in captivity with specialized electronic chips. One group of lizard lived in an entirely outdoor environment for one year. Three other groups that were subjected to alternating indoor and outdoor environments over

I am choosing to study how the PSI (pounds per square inch) of a football is affected by the temperature. I chose to study this because I like football and I always pondered this question. I believe that this is a worthwhile question to study because these studies can help improve the game as the weather gets colder. As air cools‚ it expands‚ so when a football gets colder‚ the air inside it expands. This expansion causes the air pressure to decrease. The air pressure decreases because the molecules

Examples of extreme environments on Earth are hot geysers and oceanic thermal vents‚ Antarctic sea ice‚ and oxygen-depleted rivers and lakes. Organisms that have evolved special adaptations that permit them to live in extreme conditions are called "extremophiles."

The Effect of Temperature on Solubility By Aviraj Singh Rogers 2 Background: The solubility of most solid substances is generally said to increase as the temperature of the solvent increases. However‚ some substances‚ such as ytterbium sulfate‚ do the opposite. This can be explained through the Second Law of Thermodynamics which states that “in all energy exchanges‚ if no energy enters or leaves the system‚ the potential energy of the state will always be less than that of the initial state”
