How does that explain what happened to the can? Before the can was placed into the ice bath, the temperature was very high. This meant that the vapor pressure was also high; the molecules were moving fast, hitting the sides of the can with a lot force and hitting the sides frequently. When the can was placed in the ice bath, the water molecules in the can quickly became liquid when the temperature changed. There was a drop in kinetic energy, so the vapor pressure inside of the can became extremely low.
Because salt can be dissolved in water, it is said to have high solubility. Sodium acetate also dissolves very easily in water, especially in warm water, so it has high solubility too(1). There are 2 ways to change the solubility of a solution. One way to change it is to raise the temperature because at higher temperatures most solids are extra soluble. The increase of temperature has 2 effects on almost all solutes that are solid.
This would have a positive effect in delivering more oxygen to the tissues and would be especially important if exercise was to be carried out as more oxygen is being use by the tissues. Although the left ward shift would increase the oxygen carrying capacity it could be argued that if there was a rightward shift in the oxygen dissociation curve it could be more beneficial. This shift would cause an increase in the unloading of oxygen into the tissues making more oxygen readily available to the mitochondria of those tissues. In order to determine if a left or right shift does occur the concentration of 2,3 DPG could be measured at altitude and at sea level in a native sea dweller. If in fact there is a left shift as expected there would be an increase in the carrying capacity of the
The purpose of this lab was to observe the phenomenon of resonance in an open ended cylindrical tube and use resonance to determine the velocity of sound in air at regular temperatures. A hypothesis for this lab was that if the frequency of the tuning fork increased, then the length of the tube to achieve resonance will increase because of the high amplitude of the vibration. The resonance of the open-closed tube was found through these steps. First, the tube was filled with water with an inner tube inside the outer tube. The water temperature was measured.
The developments of the plates in the world 's hull cause them. These plates don 't generally move easily and can stall out, bringing on a development of weight. It is the point at which this weight is discharged that a tremor happens. Thusly, a tremor under the water can likewise bring about a wave, as the shudder causes incredible waves by pushing vast volumes of water to the surface. Tidal waves can likewise be created by submerged volcanic ejections.
When the temperature falls below temperature of 980K, the structure is trigonal and posses the lattice boundaries a=b=c, α= β= γ ≠ 90°. The structure will transform from a α-model to the β-model and become a hexagonal unit cell. This then portrays the difference between the symmetries of the two different structures. According to Table 2, it shows the changes in cell parameters as well as volume in relation to the temperature of the metal. It therefore shows us that when temperature rises, the crystal forms will change as they are affected by changes in temperature.
Shock waves and its effect on supersonic flight Definition of shock wave – shock waves are defined as a compressional large amplitude wave evolved by abrupt change of pressure and density in a narrow region travelling through a medium, especially in air, caused by earthquake/explosion or by an object moving faster than the speed of sound. The thickness of the shocks is comparable to the mean free path of the gas molecules in the flow field. Formation – the flow consists of a large number of fluid molecules in unit volume and the transport of mass, momentum and energy takes place through the motion of these molecules. Also, the molecules carry the signals about the presence of the cylinder around the flow field at a speed equal to speed of sound. As shown in fig the
Pressure changes in the lungs are delivered by varieties in lung volume, as per the opposite relationship between the volume and pressure of a gas portrayed by Boyle's law. The mechanics of ventilation are affected by the physical properties of the lungs. On first thought, no doubt the surface strain in the alveoli would make a pressure that would bring about little alveoli to collapse and discharge their air into larger alveoli. This
As the temperature increases from 294K to 1073K, Fe-O bond distance decreases and the bond tilt angle is also smaller. Whereas for PO4, the increase in temperature causes compression which cause the bond tilt angle to decrease. At high temperature which is the beta phase of FePO4, given that the increase in volume is only related to the changing of the angles between the tetrahedral (tilting angles), the structure should not be able to expand anymore and there would be no further change in volume. In beta phase of FePO4, the volume does not expand any further as the structure is fully expanded. In the beta phase of FePO4, the bond distance decreases as the temperature increases.
Describe the agonists and antagonists that act on the ion channels and their significance. Agonists of ion channels are substances that bind into the pores of these channels and cause the channels to open and facilitate the flow of ions through them. For example, Acetylcholine (nicotinic) binds to the excitatory ionotropic Na/K receptor that is broadly distributed, including striated muscle. Similarly, Serotonin binds to the excitatory ionotropic Na/K receptor especially in the raphe nuclei, which affects the cognitive function and attentiveness. Glutamate also binds to ionotropic excitatory Na/Ca/K or NMDA/AMPA while Glycine and GABA bind to inhibitory Cl- receptor.
