would exhibit lower body temperatures than those residing on banks alongside streams due to convection of the moving water. The results of this experiment indicated a significant difference between body temperatures of the model turtles in each microhabitat. The temperatures of the samples in the stream were significantly lower than those of the samples on the bank. These results indicate that the convection from the moving stream waters provide effective means for lowering body temperature in ectotherms

Granulations doesn’t last very long‚ and it disappear really fast. Individual granulations‚ it only visible for about only minutes. Granulations on the photosphere of the Sun are caused by convection currents (thermal columns‚ Bénard cells) of plasma with in the Sun’s convective zone. Granulations are caused by convection currents because the rising part of the granules is in the center where the plasma is hotter. The outer edge of the granules is darker due to the cooler descending plasma. In addition

Styrofoam also acts as a thermal insulation. I used the tin foil because it serves as an insulator and keeps the radiant heat inside the box. Next I used insulation‚ which does what its name is‚ it keeps whatever inside of it insulated or prevents convection. I used silicone to block off the holes from the Styrofoam to make a good box for the heat to stay in. finally I used a cork on the top of my can to have the smallest hole for the heat to escape it. III. For this experiment I

The heating of brown beans‚ red cabbage‚ liver sausage and brussel sprouts was done in a water bath of 82.5°C. As can be seen in figure 1 the brussel sprouts heated up the quickest and took 11 minutes to come to a 77.5°C temperature or a 5°C lower temperature than the max. The other three heated up similarly with red cabbage taking 38 minutes‚ brown beans 42 minutes and the liver sausage taking the longest with 45 minutes. Water was added to the brussel sprouts and that did have an effect on the

space. "Heat is a measure of the average molecular motion of matter." (Convection‚ Conduction‚ and Radiation). Heat is transferred from one object or matter to another by three types of methods: convection‚ conduction‚ and radiation. "Conduction is heat transfer by direct molecular interactions‚ without mass movement of matter" (Convection‚ Conduction‚ and Radiation). "Convection is heat transfer by mass movement" (Convection). "When molecules of a liquid vaporize‚ they escape from the liquid into

Lab #7: Thermal Energy Heat is thermal energy being transferred from one place to another‚ because of temperature changes. This can take place by three processes. These three processes are known as conduction‚ convection‚ and radiation. When we place two objects with different temperatures in contact with each other‚ the heat from the hotter object will immediately and automatically flow to the colder object. This is known as conduction. Some objects make excellent conductors of heat while

Plate tectonic theory is a widely excepted theory that the Earth’s lithosphere is made up of plates‚ both oceanic and continental‚ which slowly move due to convection currents in the mantle and the asthenosphere. However‚ it is very hard to be certain as we can’t see the structure of the Earth‚ so some people do not agree with it. This theory saw the introduction of what we know today to be tectonic plates. Tectonic plates occur where there is radioactive decay in the core and temperatures are extremely

the various ways that heat can be transported in the atmosphere. In the atmosphere‚ heat is transferred by conduction‚ convection‚ and radiation. Conduction is the transfer of heat from molecule to molecule. An example of conduction would be burning your hand after touching a hot stove. Convection is the transfer of heat by the mass movement of fluid. A good example of convection is actually a microwave oven. Radiation is the heat transfer that travels in the form of a wave that releases energy when

into the loft. Without loft insulation a convection current takes place where the warm air moves through the roof space after the air at the base of the loft warms up leaving the air to escape through the roof (tiles). When the loft is insulated it is considered as a blanket trapping rising heat in the house. The convection current does not allow the uninsulated lofts to move the air in the insulation. Heat energy in the loft is transferred by the convection currents to the roof tiles. It has trapped

metabolism at 35 degrees Celsius. An hour later‚ measurements were taken again at 24-26 degrees Celsius. Minimal endothermy was determined in both experiments (Bennett 2000). The three sub factors of solar energy absorption include convection‚ conduction‚ and radiation. Convection is a continuous circulation of liquid or air that transfers thermal energy from hot to cold surfaces (Reece 2014). The process of heat gain is evident when blood transfers heat from the core of an organism’s body to the extremities
