One suggested treatment for someone who has had a stroke is to immerse the patient in a 0˚C ice water bath to lower body temperature, which prevents damage to the brain. . In a series of tests, patients were cooled until their internal temperature reached 32.0˚C. To treat a 70 kg patient, what is the minimum amount of ice (at 0˚C) that you need in the bath to keep the temperature at 0˚C? The specific heat of the human body is 3480 J / (kg˚C) and reminds us that the normal body temperature is 37˚C. The latent heat of fusion for water is 334 kJ / kg. (please show steps, formula and explanation for more understanding)
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 is transferred between the two systems or in between the systems and their surrounding by the virtue of difference in temperature. Calorimetry is that branch of science which helps in measuring the changes which are taking place in the heat energy of a given body.
