work. I predict that for temperature‚ it will not be a case of an increase in x = an increase in y. I predict that there will be a peak where photosynthesis happens the quickest at around 40-50°C. Chlorophyll is an enzyme‚ therefore it requires some heat to work‚ but if it is overheated it stops working. Enzymes work rather like a lock and key. It is important that they are a very specific shape for their purpose (in this case chlorophyll joins

Whitten‚ R. Davis‚ R.‚ M. L. Peck‚ and G. Stanley. Chemical Thermodynamics: Heat and Thermochemistry Thermodynamics & Thermochemistry Thermodynamics is the study of heat and its transformations to and from other forms of energy Thermochemistry is a branch of thermodynamics that deals with the heat involved with chemical and physical changes Objectives 1. Define thermodynamics & thermochemistry 2. Define energy‚ heat and other thermodynamic terms 3. Define enthalpy 4. Discuss thermochemical equations

The second goal was to measure the heat capacity of the constructed calorimeter. The third and fourth goal was to determine what reactions were to be investigated and what variations of the reactions would be studied. The two requirements that were kept in mind while creating the calorimeter were that it should be a good insulator‚ meaning that it does not allow for the transfer of heat between two systems in an environment‚ and that it should have the lowest heat capacity possible (ideally 0C) so

The ways that require energy are put into a category called active transport‚ while the ways that don’t require energy are put into a category called passive transport. An example of active transport is the proton pump. The proton pump is an integral part of chemiosmosis‚ and it pumps protons from an area of low concentration to an area of high concentration. This requires energy since things like to move from an area of high concentration to an area of low concentration. An example of passive transport

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 protecting objects from gaining unwanted heat. Plastic wrap insulates the heat but makes it that it is too hot to touch. Plastic

conditions of the aircraft. Fuel systems are classified according to the way the fuel is moved to the engine from the fuel tanks; the gravity feed and the fuel pump systems. The gravity feed system uses the forces of the gravity to transfer fuel from the tanks to the engine. This system is common on high wing airplanes with a carburetor engine. The fuel pump system has two

a. From 23 degrees to 28 degrees the slope of the line increases and shows a slight curve. The rate of evaporation increases with temperature since transpiration is a cooling mechanism to release heat. More stomata open as temperature increases as this allows a faster transpiration rate. Although‚ at much higher temperatures‚ plants close stomata to prevent excess water loss. b. The increasing humidity causes reduced transpiration rates. This is because atmosphere is saturated with water vapor

A place needed shelter from the prevailing south-westerly and cold northerly winds. A south-facing aspect gives most sunshine heat and light. The growth of cities‚ along with more people living in these cities and towns is called urbanisation. Settlement Patterns There
