To determine the heating and cooling curve of water Design: What we are going to do is investigate the phase changes and what the heating curve of water is. We are going to do this is by heating up 100ml of water on a Bunsen burner then adding ice cubes. Use a thermometer to measure the temperature every 30 seconds until it reaches a plateau. Hypothesis: As more time passes‚ the temperature of the water increases. Independent variable: Time Dependent variable: Changing water temperature

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

In today’s busy and hectic life‚ the average person does not get the necessary six to eight hours of sleep. They do not eat healthy foods to give their body the energy they need. As a consequence‚ they most of the time feel tired and lazy. A smart solution would be to get enough sleep every night‚ eat the right foods‚ and keep a balanced diet. However‚ because today

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
