Aim: How is heat measured? QQ: Draw a potential energy diagram for an endothermic reaction. Label key information. Do Now: What is the difference between heat and temperature? Heat: the form of kinetic energy that flows from one object to another due to their difference in temperatures. Heat flows from hot to cold! Calorie: the amount of energy it takes to raise 1.00 g of water by 1 o C Joule: the amount of work done by a force of one newton moving an object through a distance of one meter 1.00 cal = 4.18 J Practice: Make the following conversions: 1. 200 cal = 2. 1955 J = 3. 2500 J = 4. 1400 cal = “Chemistry” calories and “food” calories are not the same thing! “Food” calories are kilo calories (often spelled Calories) Specific Heat Capacity (C): the amount of heat per unit mass required to raise the temperature of that substance by 1 °C. Generally measured in J/g- o C High specific heat values means a material retains heat well
