Ethylene glycol has a lower heat capacity, so it lowers the overall heat capacity of the solution and hence the effectiveness of the cooling system. Water in a solution with ethylene glycol is also used in car engines for cooling. In countries with cold climates, it is circulated in pipes in houses to provide heating. It is often used because water is generally cheap. Water’s high heat capacity means that it loses heat slowly, which makes it an excellent cooling agent. For example, the air temperature difference in the desert between daytime and nighttime is much more significant than the temperature fluctuation near or above the surface of an ocean. On the other hand, planets that do not have such extensive water coverage as does Earth, or even places on Earth with very little water, for example, deserts, have a much larger temperature fluctuation when the amount of solar heat changes. Even if the heat generated by solar radiation is high, it takes a long time to raise the temperature of the oceans and other bodies of water, and the overall changes in temperature are very gradual. This is because a large portion of our planet is covered by water. Water forms a thermal regulation system in bodies of living organisms and plants, as well as a more global system that controls Earth’s temperature and climate. Heat Capacity and Specific Heat Capacity of Different Materials Metals
This article discusses both heat capacity and specific heat capacity because the two are related. This means that the substance is not changing between different states. Heat capacity and specific heat capacity are only calculated when the object or a substance is in a steady state (for example, a solid). Mass is not considered when calculating heat capacity. This is different from heat capacity, which measures the amount of energy needed to change the temperature of an object or matter by a given value. Specific heat capacity represents how much energy (or heat) is needed to change the temperature of an object of a given mass by a given value. To represent these properties of materials and substances, we use the terms specific heat capacity and heat capacity. If we heat up several different substances with the same amount of energy, some substances may warm up at a faster rate than others, because of the factors above that affect their diffusion rate. We can burn some gas, coal, or wood, for this purpose. If we want to increase diffusion by raising the temperature of a substance, for example by heating it, we will have to generate energy to produce this heat. The movement of molecules requires energy, and to make molecules move faster, more energy is required.
For example, if we compare water and honey, we will notice that with all other conditions such as pressure and temperature being equal, diffusion happens faster in water, because its viscosity is lower than that of honey. The movement of molecules also depends on a range of other factors, such as pressure, the viscosity of the substance, its concentration, resistance to diffusion, the distance that a molecule travels in order for the diffusion to occur, and the mass of a molecule. The greater the temperature in a substance - the more the molecules move, and the higher the rate of diffusion. Heat causes molecules to move, and this movement is called molecular diffusion.
