Rina is a physics student that enjoys hot tea. She wants to determine how much ice is needed to cool 0.210 kg of tea to an optimal drinking temperature of 57.8 C. The method Rina uses to prepare her tea results in tray she uses is 17.7 g and has a starting temperature of -5.30°C. Assume that the heat capacity of tea is the same as pure water, initial temperature of 80.8 °C. The average mass of an ice cube from the ice and that no heat is lost to the surroundings. What mass of ice mice in grams is needed to reach the optimal temperature of 57.8 °C? mice = How many whole ice cubes N should Rina use to cool her tea as close as possible to 57.8 °C? N = ice cubes
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.
