Why is biology divided into the physical and applied branches? In biology, living organisms, including their structure, function, growth, reproduction, classification, origin, and evolution are discussed. Biology also teaches how to use this knowledge to improve human life. To discuss this knowledge in detail, biology has been divided into two branches. one is physical biology in which theoretical concepts are discussed, and the other is applied biology in which the way of using theoretical knowledge is discussed. Actually, for learning and using knowledge easily and effectively, biology is divided into these two parts.

When you open the gas cylinder used for cooking, which action takes place first diffusion or effusion?

When you open the gas cylinder used for cooking, which action takes place first diffusion or effusion?

The pressures of the ingredients of body spray inside and outside of the container are not the same. The pressure is greater inside the container. When the molecules of the gas come out through small pores into a low-pressure zone from a high-pressure zone, effusion happens. Due to the application of pressure, the molecules present in body spray come out through the small pores. The spontaneous movement is blocked by the pore of the container. The bigger the pore size, the more spontaneous the movement is. When the condition becomes absolutely pressure-less, it becomes diffusion. So in the case of a body spray, first effusion takes place, then diffusion happens.
