Does all the ice melt calorimetry? Once all the ice has melted, the temperature of the liquid water rises, absorbing heat at a new constant rate. At 100oC the water begins to boil….Heat and Change in Physical State. Substance Mercury Melting Point (oC) –38.9 ΔHfus, (J/g) 11.8 Boiling Point (oC) 357 ΔHvap (J/g) 272 When […]

What are the methods of measuring resistance? Measurement of Medium Resistance (1Ω – 100kΩ) Ammeter-Voltmeter Method. Wheatstone Bridge Method. Substitution Method. Carey- Foster Bridge Method. Ohmmeter Method. Which method is used for high resistance? Two methods are used to measure high resistance, the constant voltage method and the constant current method. In the constant- voltage […]

Can an explosion trigger an earthquake? A nuclear explosion can cause an earthquake and even an aftershock sequence. However, earthquakes induced by explosions have been much smaller than the explosion, and the aftershock sequence produces fewer and smaller aftershocks than a similar size earthquake. Not all explosions have caused earthquakes. Can a nuke cause a […]

What is the balancing? A state of equilibrium or parity characterized by cancellation of all forces by equal opposing forces. 3. The power or means to decide: matters that fell outside the judge’s balance. What are different types of balancing? There are three different types of balance: Symmetrical, asymmetrical and radial. What are the 4 […]

When a parallel plate capacitor is being charged by a DC battery Why does a galvanometer? Answer Expert Verified During charging and discharging of the capacitor, there is a flow of charge from the battery towards the plates of the capacitor, which produces a conduction current in the circuit. Hence, the galvanometer present in the […]

How quickly do TMS work? Compared to most antidepressants, which usually take about six weeks to show results, TMS works relatively quickly. Patients report changes in mood starting as early as the first week of treatment. Furthermore, unlike antidepressants, TMS is not something you’ll need every day for the remainder of your recovery. Can you […]

Which describes the movement of cells? Cell movement or motility is a highly dynamic phenomenon that is essential to a variety of biological processes such as the development of an organism (morphogenesis), wound healing, cancer metastasis and immune response. In all these examples, cells reach their target by crawling. What describes simple diffusion? In biology, […]

Are 2s and 2p degenerate? The 2s and 2p orbitals have the same energy for hydrogen. They are said to be degenerate energy levels, all the same. When the electron is held in the 1s orbital, it is said to be in its ground state, its lowest energy state. When the electron is a higher […]

Why are evenings cooler than afternoons? Answer. Because in afternoon the sun is on the top and the rays of sunshine comes direct to the earth so we feel warmer and in morning and evening the sun is slightly to the earth so we feel colder then afternoon. Why does the coolest temperature of the […]

What is the cycle of rain called? As the water vapor rises higher and higher, the cool air of the atmosphere causes the water vapor to turn back into liquid water, creating clouds. This process is called condensation. When a cloud becomes full of liquid water, it falls from the sky as rain or snow—also […]
