Mode of energy transfer in fluids is convection.
There are two main types of thermal energy - solar and geothermal. Solar energy is renewable and sustainable, and after the initial investment, is free. Geothermal energy is renewable, sustainable, and clean reducing reliance on foreign energy sources. The disadvantages are mostly financial because of the start up costs. While solar is an individual form of energy, geothermal requires large generation plants. Also solar viability is dependent on the amount of sunshine the area receives.
Energy is neither created nor destroyed; the total energy remains the same(1st law of thermodynamics). Also, theoretically the maximum efficiency of a thermodynamic reaction is 100%- but in reality a portion of the input energy is transformed into other forms like heat, sound, light or a change in the internal order of the system. Therefore energy is not lost in a closed system just transformed into many different types of energy.
Transfer of heat in nature occurs through three ways: conduction, convection and radiation. Conduction takes place in solids. Convection in liquids and gases. Radiation takes place in all three media as well as in vaccum.
Thermal insulation hinders the loss of heat energy. Clothing acts as thermal insulation for human bodies. In buildings, these materials are often used as thermal insulation: plant straw, wood fiber, cellulose, polystyrene, vermiculite, urethane foam, perlite, recycled cotton denim.
convection means when something is heated it expands or conducts eg. metal is heated it contracts when it is cooled it contracts.

Not likely. Atoms are mostly empty space.
In a conventional oven it's mostly conduction,with a bit of air convection thrown in.There are "ovens" (as seen on TV ... mostly at 3AM) that use hot air and forced convection as the main heat transfer technique.
Thermal Energy
Mostly the kinetic energy of particles due to heating is called thermal energy Temperature is a measure of heat
Mostly by wind and current.
Convection.
Density determines how far apart molecules of a material are from one another, i.e. Density is the mass per unit of space. Due to this, density is related to the rate of heat transfer or thermal energy transfer. Thermal energy being transferred relies on the difference in the internal energy of molecules, mostly kinetic energy, as when heat is transferred, these molecules exchange energy by hitting into each other. By doing so, eventually thermal equilibrium is established. Summary - Density is related to the rate of heat transfer between two systems.
Bond Dissociation Enthalpy is the energy required for breaking the bonds. This energy is supplied mostly by giving thermal energy (Heat).
