Convection is a way of transferring thermal energy. It is possible in fluids only. Fluids include liquids and gases. Milk and water are liquids, whereas the atmosphere is a gas. So convection is not possible in iron, which is a solid.

Convection in Particles

Convection is the transfer of heat through the movement of fluids (liquids or gases). In the case of particles, convection is not possible in solid particles due to their rigid structure.

Iron
- Iron is a solid particle with a fixed shape and volume.
- Solid particles like iron do not exhibit the fluid-like movement required for convection to occur.
- As a result, convection is not possible in iron particles.

In contrast, fluids like milk, water, and the atmosphere are capable of convection due to their ability to flow and move freely. Convection plays a significant role in the movement of fluids and the transfer of heat within them.

However, these reservoirs are not like the giant man-made lakes that might come to mind; they are underground. In fact, a reservoir occurs in a rock that looks on the surface like any other. The oil and gas pool in millions of tiny pores in the rock. Porous rocks include sandstone, limestone, shale, and many more. There are several factors affecting porosity (the ability to store ﬂuid in the open spaces located between rock particles). Among these factors are the nature and characteristics of the sand and other sediment that accumulate to form rocks. The sand particle size is not critical to porosity, but the uniformity or sorting of the sand grains greatly effects porosity. Uniform or well-sorted sand will tend to be more porous than poorly sorted sand.Experiment 1In a laboratory, a scientist wanted to determine the porosity of 4 samples of different rocks. The scientist recorded the mass of the rock samples prior to the experiment. To measure porosity, the samples were soaked in water and the mass of the samples was recorded periodically. A highly porous rock would have a signiﬁcant increase in mass the longer it soaked in water, eventually reaching the point at which it could no longer absorb any more water (saturation point). The data was recorded in Table 1.Experiment 2Geologists in Arizona were interested in the porosities of different varieties of sandstone. They documented the relationship between porosity, density, sand particle size, and the uniformity or sorting of the sand grains. The geologists found that, in general, neither density nor particle size affected the porosity if the particles were uniform. However, they did ﬁnd that in samples with a wide variety of particle sizes, the porosity was generally lower.

A particle accelerator functions by exerting a magnetic field on charged particles which are shot into the accelerator. The magnetic field causes the charged particles to move around in a circle of radius R that can be predicted by the following equation, where mp is the mass of the particle in kilograms, v is the initial speed at which the particle was shot in meters per second, q is the charge of the particle in Coulombs, and B is the strength of the magnetic field in Tesla.R=mpv/qBA proton weighs approximately 1 amu (atomic mass units) and has a charge of 1.6∗10−19 C. An electron has the same magnitude of charge, but it has about 1/1800of the protons mass. What would happen to radius R if we were to suddenly switch the particle in the accelerator from a proton to an electron, keeping all of the other conditions the same?
