PHYS 1500 - Energy and Matter- Spring 2020 Jacqueline MWB Ch 18 HW Think And Solve 18.40 22 of 22 Review Constants A power station with an efficiency of 0.4 generates 10 W of electric power and dissipates 1.1x10° J of heat energy each second to the cooling water that flows through it, which increases its temperature by 3.5 Celsius degrees. Part A Knowing that the specific heat of water in SI units is 4184 J/kg °C, find what mass of warmed water flows through the plant each second. Express your answer to two significant figures and include the appropriate units. HA Value Units т 3 Submit Request Answer < Return to Assignment Provide Feedback GarencorCs II
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.
A power Station with the efficiency of .4 generates 10 to the eight power watts of electric power anticipates 1.1×10 to the eighth power joules of heat energy each second to the cooling water that flows through it which increases as temperature by 3.5 Celsius degrees knowing what to specific heat of water in SI units is 4184 j/kg degrees Celsius find what mass of warm water flows through the plant each second
