What is the specific heat of water vapor?

Specific heat water vapor: 1.996 kJ/kgK =0.4767 Btu(IT)/(lbm °F) or kcal/(kg K) Specific Weight (at 4 oC): 9.806 kN/m3 = 62.43 lbf/ft.

How much heat is released condensation?

Heat of Vaporization and Condensation When 1 mol of water vapor at 100°C condenses to liquid water at 100°C, 40.7 kJ of heat are released into the surroundings.

How hot is steam condensate?

130°F to 225°F

Are heat and temperature the same thing?

In thermodynamics, heat and temperature are closely related concepts with precise definitions. Heat, qstart text, q, end text, is thermal energy transferred from a hotter system to a cooler system that are in contact. Temperature is a measure of the average kinetic energy of the atoms or molecules in the system.

What are the three ways heat can be transferred?

What is needed for heat transfer to take place is a difference in temperature between two objects. Without this difference, no heat transfer can take place. Heat can be transferred in three ways: by conduction, by convection, and by radiation.

How do you distinguish between temperature and heat give examples?

Heat is a measure of change, never a property possessed by an object or system. Therefore, it is classified as a process variable. Temperature describes the average kinetic energy of molecules within a material or system and is measured in Celsius (°C), Kelvin(K), Fahrenheit (°F), or Rankine (R).

Does all matter contain heat energy?

All matter contains heat energy. Heat energy is the result of the movement of tiny particles called atoms, molecules or ions in solids, liquids and gases. Heat energy can be transferred from one object to another. The transfer or flow due to the difference in temperature between the two objects is called heat.

What are the 5 sources of heat?

Heating Energy SourcesGas Fired Water Heater. Here at Radiantec we often recommend the use of domestic water heaters instead of expensive boilers. Oil Fired Boilers or Water Heaters. Oil can be less expensive than gas in some locations at this time. Wood or Coal Heaters. Solar Collectors. Radiant Retrofit. Electric Heat. Geothermal.
