HG-1 THE HEAT OF FUSION OF ICE Introduction When heat flows into a system there are a number of things that can happen. One result could be a temperature rise. Or‚ the system might even catch fire. A third possibility is a change of state. As you know‚ matter exists in three states (or maybe four‚ the fourth being a plasma)‚ solid‚ liquid and gaseous. At different temperatures‚ the same substance may be in different states. Each state is characterized by the way the interatomic forces act. In solids

I. Temperature Measurement 1. A thermometric property is a physical property that changes in a known way with temperature‚ and can therefore be used to measure temperature. The substance used as a thermometer must have a property that varies proportionally / linearly with temperature. [ In other words: When objects are heated or cooled‚ their temperatures change‚ along with some of their properties‚ these properties are known as Thermometric Properties.] Two commonly used thermometric properties

Physics takes place in every aspect of our lives. From the time we get out of bed until the time we get back into our bed. Physics influences are far beyond the classroom. If you’ve ever wondered what makes lightning‚ why baseball pitchers throw so fast‚ how track stars can run so fast‚ how Lebron James can jump so high. Why some people are stronger than others‚ how that tiny computer can do complicated problems‚ or how long it takes light from the sun to reach us. All of these questions are studied

6. Applications * Is it possible to add heat to a body without changing its temperature? Yes. It is possible to add energy to a body (in the form of heat) and not raise its temperature by causing a phase change. When you heat ice it takes energy to convert it from ice to water‚ but does not change the temperature of the body until it is all converted. The principle behind this is what we call latent heat. It refers to the energy (or heat) required to change the state of a substance without changing

Week #7 Chapter 10 Static and Current Electricity Exercises (p.221) 6. Strictly speaking‚ will a penny be slightly more massive if it has a negative charge or a positive charge? Explain. A negative charge because when it is negatively charged electrons are added to the penny. 17. What is the voltage at the location of a 0.0001 C charge that has an electric potential energy of 0.5 J (both voltage and potential relative to the same reference point)? Potential = energy Charge = 0.5 J / 0.0001

laboratory. Report by Phillip Chidavaenzi The government laboratory examined samples of bottled water from several suppliers following an inquiry by NewsDay and exposed seven of them as unsafe for drinking. The water being sold under trade names Ad Life‚ Well Pure‚ Aqua Crystal‚ Century and Revive had harmful organisms and was not safe for drinking‚ while that sold under the names LeauChoisie and Aqualite had high chemical compositions. The laboratory falls under the Ministry of Health and Child

The Yoruba People of Nigeria Among the many tribes found in Africa‚ the Yoruba People of Nigeria are among the most popular and well known. The Yoruba are the tribe that many Africans confess that their family roots started from and therefore follow the religion and culture of the Yoruba. These people are indigenous to the Southwestern parts of Nigeria and Benin. They may not be the only tribe in Africa‚ but they certainty have an interesting culture along with one of the oldest ancestry lines

My Journal Monday (09.07.2012) We arrived at Bengaluru International Airport around 5.25 pm and we set our watches to Bengaluru time which is 2½ hours later than Malaysian time. After 4 hours in Airasia AK1212‚ we finally reached Bangalore for our conference tomorrow. We stayed in Woodlands Hotel and it is about 1 hour journey from the airport. Our conference will be held in ITC Gardenia‚ the first green hotel in the world which is just across the road from where we stayed. Tuesday (10

The Jewish Scripture starts right at the beginning of time itself‚ where God created the universe‚ and only then did he create the earth (Genesis 1). Right from the beginning God has had an intimate connection between God and the world‚ and this connection is believed to continue throughout time. From the moment god created humanity (Gen. 1:26)‚ we were created for the one purpose to protect the earth. But it is in the story of Noah that we perhaps truly learn about the role that God had created
