point happens when a substance has a high enough temperature and pressure that both liquid and gas can exist at the same time. This state is called a critical point. Now‚ when a state of matter changes from one state to another is called a phase shift. Phase shifts are extremely important and most commonly observe phase shifts daily. For an example‚ when water freezes into ice‚ or the water in the shower turns to steam. To begin to start describing how a phase shift works we must understand factors

Temperature and enzyme activity Aim: To determine the effect of which the temperature of the enzyme has on the rate of the enzyme catalysed reaction. Hypothesis: The rate of reaction of an enzyme catalysed reaction will increase as the temperature of the enzyme approaches the optimum temperature. Surpassing the optimum temperature will result in a drop in enzyme activity. Materials: 6% hydrogen peroxide Liver suspension 10 test tubes 4 beakers Thermometers Measuring cylinders Test

Ideal Temperature for junket Aim- To discover the optimum temperature for junket to solidify Hypothesis- That the optimum temperature will be between 35-40°C Independent variable- Temperature (10‚ 40‚ 60 degrees) Dependant variable- Time taken for Junket to set Control- 2 clearly marker test tubes will be placed under each temperature condition‚ one with junket and one without‚ to clear the complication that it might be the temperature that is reacting with the milk and solidifying it instead

conducting this experiment to identify how temperature affects the solubility of salt. To add on‚ by making this experiment we could see how temperature affects the solubility of a substance‚ the maximum number of solute particles that can dissolve in solvent particles. Also‚ how by changing the temperature we could see how if the solubility of the solute would either increase or decrease. This experiment connects with information we learn in class because of how in class we learned about the two

Investigation into the photosynthetic activity of isolated chloroplasts from spinach beet to various light conditions. Introduction Chlorophyll‚ an important pigment in chloroplasts‚ is an essential component in photosynthesis; converting electromagnetic radiation from the sun into potential chemical energy. Photons excite electrons in chlorophyll which move through the electron transport chain‚ resulting in energy being stored in the bonds of ATP and NADPH. The flow of electron through the electron

coagulate‚ the independent was the temperature of the water bath and the control was the deionised water and milk solution. These variables allowed for the experiment to be conducted accurately‚ with unexpected results. This is due to the enzymes being most active at 60ᵒC‚ it was that results were going to be most active at the 41ᵒC which is close to human body temperature. When we compare the enzyme in the low temperatures to the enzymes in the higher temperature we observed that the enzymes were

interesting to know how different environmental factors affect the rate of transpiration. There are different environmental factors‚ such as light intensity‚ humidity‚ wind and temperature that affect the rate of transpiration. Transpiration is a topic 9 in our Biology higher level book. I have read all the information through this chapter and researched some extra information. Based on this information that I had known I decided to take experiment of environmental factor of wind temperature. I am aware

The effect of temperature on the rate of maggot movement Research and Rationale This experiment is aiming to analyse the behaviour of maggots when they are exposed to light and the effect of that on their movement rate. Behaviour is the way in which animals respond to external factors is known as behaviour. As animals become bigger their behaviour becomes more complex. This is because larger animals tend to have a more complex nervous and hormonal system. Two of the types of behaviour are called

AUTOMATIC TEMPERATURE DETECTING SYSTEM Author: NETAJI.PANIGRAHI B.Tech e.mail:netajipanigrahi@gmail.com 1 CHAPTER 1 INTRODUCTION The Automatic Temperature Detecting System is an embedded system application which has the capability of detecting temperature of the environment. The behavior of the system is based on sensor. Based on sensing information the microcontroller will respond. This system works on 5V power supply. Here Microcontroller plays a major role which takes inputs from sensor

destroying our world indirectly which means we do not just go and kill those entire animals‚ but what has caused their extinction is due to “Climate Change” that is the result of the Natural Causes and Human Activities. We used to look at how natural causes have contributed to climate change‚ but human is now even playing a bigger role in causing climate change. Climate can be defined as the average weather effected by slow features such as oceans‚ precipitations‚ and clouds (Slaght‚ 2009‚ p34-41). Out
