Energy transfer

The flow of energy from one region to another region is referred to as energy transfer. Since energy is quantitative; it must be transferred to a body or a material to work or to heat the system.

Molar Specific Heat

Heat capacity is the amount of heat energy absorbed or released by a chemical substance per the change in temperature of that substance. The change in heat is also called enthalpy. The SI unit of heat capacity is Joules per Kelvin, which is (J K-1)

Thermal Properties of Matter

Thermal energy is described as one of the form of heat energy which flows from one body of higher temperature to the other with the lower temperature when these two bodies are placed in contact to each other. Heat is described as the form of energy which…

Chapter 17, Problem 17.36E

BIO Treatment for a Stroke. One suggested treatment for a person who has suffered a stroke is immersion in an ice-water bath at 0°C to lower the body temperature, which prevents damage to the brain. In one set of tests, patients were cooled until their internal temperature reached 32.0°C. To treat a 70.0-kg patient, what is the minimum amount of ice (at 0°C) you need in the bath so that its temperature remains at 0°C? The specific heat of the human body is 3480 J/kg · C°, and recall that normal body temperature is 37.0°C.

While hanging out in Lab, you decide to conduct another calorimetry experiment, but this time, you want to do it on a bit larger scale. You place 3.8 kg of water in a large aluminum can that has a mass of 15 kg. You heat the water and can up to an initial temperature of 80◦ C, and then slowly add 400 g of ice that has an initial temperature of −10◦ C. You stir the ice and water until all of the ice melts, and the system comes to an equilibrium temperature of 32◦ C. You feel good about things until you realize that you did not cover the aluminum can and that some heat was lost to the environment during the experiment. Use the information provided to calculate the amount of heat that was lost to the environment.

Problem 5: You are on your way to a party when the host asks you to pick up a bag of ice. At the grocery store you grab a 5-kg bag that was kept at a temperature of -5.2°C. When you get to the party, you find a large cooler to put the ice in. There is already 32 L (i.e., 32 kg) of water in the cooler at a temperature of 19°C. You toss the ice into the water and close the lid. The specific heat and latent heat of fusion for water are 4186 J/(kg.C) and 3.34 x 10 J/kg, respectively. The specific heat of ice near its freezing point is 2000 J/(kg.°C). D A Find the temperature, in degrees Celsius, of the water in the cooler after the party.

Problem 15: You are on your way to a party when the host asks you to pick up a bag of ice. At the grocery store you grab a 6-kg bag that was kept at a temperature of -4.6°C. When you get to the party, you find a large cooler to put the ice in. There is already 31 L (i.e., 31 kg) of water in the cooler at a temperature of 19°C. You toss the ice into the water and close the lid. The specific heat and latent heat of fusion for water are 4186 J/(kg⋅°C) and 3.34 × 105J/kg, respectively. The specific heat of ice near its freezing point is 2000 J/(kg⋅°C). Find the temperature, in degrees Celsius, of the water in the cooler after the party. Assume the ice maintains its temperature on the way to the party and the cooler is well insulated.
