Joule`s Law and Heat Transfer Name
... To do this we need to measure the amount of electrical energy we supply and the amount of heat energy the water, calorimeter-cup, and heater gains. Then neglecting heat loss to the room, we could find the relationship between calorie and Joule. Electrical energy, E is given by: E = I V t; where I = ...

Section 12.1 Temperature and Thermal Energy
... One way to increase the temperature of an object is to place it in contact with a hotter object. Heat – energy that flows as a result of a difference in temperature. The symbol for heat is Q. Heat is a form of energy thus it is measured in Joules. It is the energy transferred because of a difference ...

Heat & Energy
... • Heat causes the atoms or molecules of any material to “jiggle”. • When jiggling they need more room, so the volume increases with temperature (normally). • Water is an exception: with the temp going down between 4 deg and 0 degrees, water will expand, and on freezing will increase volume by 9%. • ...
