তাপীয় শক্তি: উত্স এবং 5টি গুরুত্বপূর্ণ শিল্প অ্যাপ্লিকেশন

তাপ শক্তি:

Thermal energy or heat energy is generated from the vibration of molecules or atoms within a substance. The quicker the atom move, the more energy it will hold along with it and more heat will be generated too.

Thermal energy is the energy originated by a scheme due to the movement of particles inside its volume. As we know, a system is nothing but a collection of objects within some boundaries. As thermal energy is generated due to the movement of particles, it’s one type of kinetic energy. In most fossil fuel-based power plant thermal energy is converted to the electrical form of energy.

Examples of thermal energy:

  • The energy from the sun.
  • Burning in an oven.
  • The room heater’s heat productions.

What are the primary resources of thermal energy?

Most common thermal energy source is solar energy. No matter it is a fine day or a cloudy day, people can always get সৌরশক্তি. There are also many sources such as combustion of solid or liquid fuel, ভূ শক্তি, etc. There are 4 key resources:

  • সূর্যালোক.
  • Chemical energy conversion.
  • Electrical power conversion.
  • Heat from Nuclear reaction.

তিন ধরণের তাপ স্থানান্তর:

  • পরিবহন
  • পরিচলন
  • রেডিয়েশন

Heat is generally transferred in a combination of these 3 forms or either one.

What is the unit of thermal energy?

  • Joule (J) in SI unit.
  • The typical unit for the rate of heat transfer is the watt (W), defined as 1 joule/sec.

নির্দিষ্ট তাপ কি?

The specific heat is the quantity of heat/unit mass essential to increase the temp by 1oC.

Relationship of Heat transfer and temp. change:

প্রশ্ন = এমসিএটিটি

কোথায়,

  • The Q is value of heat transfer.
  • m is the mass of the material.
  • ΔT is the temp. change.
  • c is specific heat.

Relation to heat and internal energy

থার্মোডাইনামিক্স:

তাপগতিবিদ্যা is the studies of thermal energy and its movement from one place or form to other one.

শক্তি সংরক্ষণের আইন

Conservation of energy is a principle that explains

Energy can never be created or destroyed, but it can be transformed from one type to other.

Once heat is generated from some other form of energy then its in the form of thermal energy, while work can apparent the aforementioned in mechanical energy.

Industrial Oven:

  • These are hot chamber utilized in diverse of manufacturing process, such as drying-up, baking purpose, heat treatment processes etc.

তাপ:

  • Heat exchangers are extensively employed in industry i.e, refrigerator, air-cooler, car-radiator, space heater, power production, and chemical processing.

Thermal Torch:

  • It’s a tool that can generate high temperature in the presence of pressurized O2 to may apply as cutting thick metal sheet.

ভূ শক্তি:

ভূ শক্তি is also one type of thermal energy, is reserved under the Earth’s surface. This originated from both the original formation of the planet and the radioactive decay of the minerals and elements.
