1. How does the study of heat relate to the kinetic theory of matter? Theory for ideal gases makes the following assumptions the gas consists of very small particles, all no zero mass. The number of molecules is large such that statistical treatment can be applied. These molecules are in constant, random motion. The rapidly moving particles constantly collide with the walls of the container.
2. What is heat? Heat is energy that is transferred from one body, region or thermodynamic system to another due to thermal contact or thermal radiation when the systems are at different ...view middle of the document...
7. What are the various sources of heat?
The capacity of a physical system to perform work is called energy. There are different types of energy, such as heat energy, mechanical energy, light energy, sound energy and electric energy. Heat energy is produced when there is a transfer of heat from a warm object to a cool object. This is an important form of energy as it is essential for day-to-day activities like cooking, ironing and the heating of water. Any object that can be used to derive heat is considered as a source of heat energy. There are many sources of heat energy. The sun is a part of our solar system. Thus, it is a natural source of heat energy. Sunlight is important for the existence of all living organisms on the planet. This form of heat energy is also called solar energy. The heat energy that is found from the Earth is called geothermal energy. Sustainable and clean geothermal energy can be found in the hot water and rocks present in the shallow ground. It is also found in the molten rocks available in the extreme depth of the Earth. The air around us is a very common source of heat energy for heat pumps. Exhaust air is also a good heat source for...
