Experiment 3: Solution Calorimetry: Thermodynamics of Potassium Nitrate II. Abstract A determination of thermodynamic variables of KNO3 is presented. KNO3 was heated and dissolved in varying volumes of distilled water. Upon dissolution‚ the KNO3 solution was removed from heat and the temperature was recorded once crystals formed. For each solution‚ ∆G the Ksp were found with the temperature and molarity values. ∆H and ∆S were found through the linearization of the data with

This model would be sold to retailers for $375. The variable cost of this unit is $225. The demand for the new Model LX4 is estimated to be 300 units per year. Sixty percent of these unit sales of the new model

Nita’s looked at the costs for the year. The restaurant wanted to see what some of their fixed and variable costs were for the year. They also wanted to make sure they remain in their relevant range. The costs focused on were the cost of hamburgers (raw materials) and the cost of building rent. It was determined that the raw materials were the variable costs because the cost will vary based on production of hamburgers. A variable cost is a cost that will change in direct proportion to changes in

Variable costing and absorption costing are the two most commonly used methods of inventory costing for manufacturing companies. The inventory method of variable costing takes place when total direct and indirect variable manufacturing costs are included within inventoriable costs. Fixed manufacturing costs however‚ are considered costs of the period under variable costing. The next method of inventory costing‚ absorption costing‚ includes all variable manufacturing costs as well as fixed manufacturing
