Concept explainers

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 18, Problem 64GP

In humid climates, people constantly dehumidify their cellars to prevent rot and mildew. If the cellar in a house (kept at 20°C) has 115 m² of floor space and a ceiling height of 2.8 m, what is the mass of water that must be removed from it in order to drop the humidity from 95% to a more reasonable 40%?

220 volts is supplied across 1200 winding of the primary coil of the autotransformer.If 1650 windings are tapped, what voltage will be supplied to the primary coil of thehigh-voltage transformer?2. A kVp meter reads 86 kVp and the turns ratio of the high-voltage step-up transformeris 1200. What is the true voltage across the meter?3. The supply voltage from the autotransformer to the filament transformer is 60 volts. If theturns ratio of the filament transformer is 1/12, what is the filament voltage?4. If the current in the primary side of the filament transformer in question 3 were 0.5 A,what would be the filament current?5. The supply to a high-voltage step-up transformer with a turns ratio of 550 is 190 volts.What is the voltage across the x-ray tube?

220 V is supplied to 800 primary turns of an autotransformer. What will the outputvoltage be across 200 secondary turns? 2. A filament transformer has a turns ratio of 1:20. What current must be supplied to theprimary windings if 5 A is required by the filament? 3. The filament transformer in the previous question is supplied with 150 V to theprimary side. What is the secondary voltage? 4. 440 V is supplied to 1000 primary turns of an autotransformer. If the desired outputvoltage is 100 V how many secondary turns must be tapped?
