Which liquid has the weakest intermolecular forces? Oil- Only London Dispersion Forces (the weakest intermolecular force) Water- London Dispersion, Dipole-Dipole, and Hydrogen Bonding. Which has stronger intermolecular forces water or alcohol? Water had the strongest intermolecular forces and evaporated most slowly. The strength of the intermolecular forces in isopropyl alcohol are in between water and […]
Why is current directly proportional to potential difference?
Why is current directly proportional to potential difference? The current in a circuit is directly proportional to the electric potential difference impressed across its ends and inversely proportional to the total resistance offered by the external circuit. The greater the battery voltage (i.e., electric potential difference), the greater the current. Is potential difference directly proportional […]
Does a closed system have potential energy?
Does a closed system have potential energy? In energy balance equation for the closed system, the energy change of the system is described as the energy change of internal energy, potential energy and the kinetic energy. For energies in transit (the energies transferring between system and surrounding), only two types of energies are involved: the […]
What are sensory receptors?
What are sensory receptors? Sensory receptors are dendrites of sensory neurons specialized for receiving specific kinds of stimuli. Sense organs (such as the eyes and ears) consist of sensory neurons with receptors for the special senses (vision, hearing, smell, taste, and equilibrium) together with connective, epithelial, or other tissues. What are the three levels of […]
How do you determine seeing conditions?
How do you determine seeing conditions? seeing conditions are mainly measured in arcseconds, even the scales are sometimes approximated to the arcseconds. The maximum is divided into a half. The width in the half of maximum shows the value of seeing as the diagram below show. It is determined that a bigger value of FWHM […]
What is the H band in a sarcomere?
What is the H band in a sarcomere? H-band is the zone of the thick filaments that has no actin. Within the H-zone is a thin M-line (from the German “Mittelscheibe”, the disc in the middle of the sarcomere) formed of cross-connecting elements of the cytoskeleton. What is the H band? In infrared astronomy, the […]
What are the three parts of a conclusion?
What are the three parts of a conclusion? Examine the three steps of an effective conclusion: restatement of the thesis, review of the main points, and concluding device. What are the three functions of a conclusion? The three primary functions of a conclusion are to restate the thesis, review the main points, and use a […]
What is the tiny tube in the thermometer called?
What is the tiny tube in the thermometer called? The liquid-in-glass thermometer is a well-known temperature-measuring instrument that is used in a wide range of applications. The fluid used is normally either mercury or colored alcohol, and this is contained within a bulb and capillary tube, as shown in Figure 14.18(a). What does narrow inner […]
What are the 5 shifters of supply?
What are the 5 shifters of supply? Supply shifters include (1) prices of factors of production, (2) returns from alternative activities, (3) technology, (4) seller expectations, (5) natural events, and (6) the number of sellers. When these other variables change, the all-other-things-unchanged conditions behind the original supply curve no longer hold. What causes increase in […]
Is physics the hardest science?
Is physics the hardest science? A-Level Physics is considered as one of the hardest courses due to the amount and complexity of material as well as the difficulty of exam questions. Even though, the subject is quite interesting and compelling for many of the students. How old are 12th graders? Stamford American International School Grade […]
