most environmentally friendly way of drinking from a cup or mug? Reusable cups are usually the preferred method as long as the cups get used a lot. As for disposable cups‚ the main three choices are paper‚ styrofoam‚ and plastic. Plastic cups are the cheapest to purchase but they can’t be used for hot drinks. Pricewise‚ plastic cups cost $11 for 1000. Styrofoam costs $25 for 1000. Paper cups cost $80-120 for 1000. 100% compostable paper cups costs around $100 for 1000 made from natural corn starch

Aim • To calculate the SHC of water • To see how accurately I can measure a known quantity Research Question • Will the experiment carried out give us a good approximation of the SHC of water? Hypothesis • The result we will get as the SHC of water will not be exactly the same as the literature value‚ but will be a very close figure to the literature value of the SHC of water as there will be some limitations to our experiment. Variables Independent: temperature of water Dependent:

INTRODUCTION Whenever two objects with different initial temperatures are put in contact with each other‚ the warmer one will cool down‚ and the cooler one will warm up‚ until they reach the same temperature. We now know that this has to do with the motions of molecules: what we sense as temperature is related to the average kinetic energy of the molecules of each material: the faster they’re vibrating around‚ the hotter the object feels. We can sidestep this molecular picture by dealing with

evaporating faster and it felt cooler. The alcohol drew heat from the body as it’s evaporating thus creating a greater heat loss and temperature change. 3 Skin Prints Different areas of the skin have different skin prints. A fingerprint has a loop design‚ whereas the skin print of a palm is straight and linear. The lines of a wrist print are interconnected and narrow. The skin print of an elbow is unorganized‚ in which the lines go in many different directions forming irregular shapes. 4 Touch Points

bacteria from reproducing. There are two different kinds of chemotherapeutic agents. The first kind is an antibiotic‚ which slow down the growth of microorganisms. The second kind of chemotherapeutic agent is synthetic drugs. Synthetic drugs are artificially made in a laboratory. Chemotherapy began in the 1940s and is now a multi-billion dollar industry. Different antibiotics and synthetic drugs all have different modes of actions and can have several different possibilities of side effects. Antibiotics

Unit 4 Assign 2 Explore and Discuss Assignment CUPS Server CUPS consist of a print spooler and scheduler‚ a filter system that converts the print data to a format that the printer will understand‚ and a backend system that sends this data to the print device. CUPS uses the Internet Printing Protocol (IPP) as the basis for managing print jobs and queues. It also provides the traditional command line interfaces for the System V and Berkeley print systems‚ and provides support for the Berkeley print

ADI Lab Report Every living thing is made up of cells. All cells have some part in common. Some multicellular cells are highly specialized and carry out some very important functions. One of the special cells are red blood cells‚ their functions‚ transporting oxygen from the lungs to the cells in the body. Red blood cells look like little discs. Red blood cells can change their shape‚ this ability allowing them to squeeze through capillaries without breaking. Our task is to Design and carry out an
