We know that chemical, mechanical, electrical and nuclear phenomenon create thermal energy. Combustion (burning) is chemical, and we know that creates thermal energy. Mechanical action creates heat, and your vehicle's brakes know this well. Electrical energy can be used to create heat in resistive heating elements. Nuclear reactions result in a jump in the energy of atoms and molecules involved, and this is expressed as heat.

1. The main source is the sun. Even though rocks seem like they emit heat, they really got their heat initially from the sun. 2. Radioactive substances emit their own energy and heat. 3. Warmblooded animals emit heat. However, they make the energy from the food they eat which ultimately came from the sun. 4. Electricity. Electricity can be used to make heat and light. 5. Other stars from other solar systems emit their own light.
The five primary sources of heat and light are the sun, fire, electricity, friction, and chemical reactions. The sun is the ultimate source of heat and light on Earth, emitting both in the form of electromagnetic radiation. Fire produces heat and light through the exothermic chemical reaction of combustion. Electricity generates heat and light through the flow of electrons in a circuit. Friction creates heat and light when two surfaces rub against each other, converting mechanical energy into thermal energy. Chemical reactions such as oxidation can also produce heat and light as byproducts.
The heat transfer coefficient for aluminum oxide varies depending on factors such as temperature, surface roughness, and material properties. In general, for aluminum oxide in air at room temperature, the heat transfer coefficient can range from 5-25 W/m^2*K. For more precise values, it is recommended to consult specific sources or conduct experiments.
The specific heat capacity of the material is 10 J/gK. Calculate the heat energy using the formula Q = mcΔT where Q is the heat energy, m is the mass, c is the specific heat capacity, and ΔT is the temperature change. Thus, Q = 5g * 10 J/gK * 5K = 250J.
