Heat Loss Investigation

The heat loss survey is aimed at changing the surface area and volume ratio of graduate student objects to cause changes in heat loss and retention. INTRODUCTION Large animals tend to retain heat more than small animals because of their large surface area to volume ratio. This is what I tried to prove by experiment. Here is an example. In winter, Robin loosens his wings to keep more heat. Doing this will result in a spherical shape and improved heat insulation.

The purpose of this experiment was to investigate and discover the relationship between heat loss (water) and surface area to animal volume ratio. To investigate this, we use three different volumetric flasks (equivalent to animals) so that different surface areas are filled with water. I predict that the heat loss of water in a 100 ml flask will be faster than that in a 250 ml flask, almost double that in a 500 ml flask. This is because the surface area of ​​a 100 ml flask is about twice that of a 500 ml flask. For example, if a 100 ml flask loses 1 ° C per minute, it is predicted that a 500 ml flask will be halved by 1/2 ° C per minute To do.

Essay.com investigates and finds the relationship between heat loss (moisture) and the surface area for animal body surface area.

Please investigate the relationship between the heat loss (moisture) and the surface area to the animal's body surface area.

It is best to understand the term "heat" before studying the concept of heat loss and insulation to prevent heat loss. The term "heat" can be defined as "interaction between two substances, which is caused by their temperature differential in communication" (Moss, 1998, p. 2). The essence of heat is not constant anywhere, but it moves from one place to another. However, this movement depends on the temperature of the place. Heat can disappear in various forms such as conduction, penetration (Parker, 1997).

Latent heat loss is also called heat loss due to evaporation and occupies most of body's heat loss. As the temperature in the center of the body rises, the body stimulates the sweat glands of the skin and brings extra moisture to the surface of the skin. After that, the liquid is converted to steam to remove heat from the body surface. The rate of heat loss due to evaporation is directly related to the vapor pressure of the skin surface and the amount of moisture present in the skin. Therefore, when the skin is completely wet, maximum heat transfer occurs. The body loses moisture by evaporation, but the maximum heat loss occurs while physical activity is increasing.
