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 is one of the most important developmental tasks in late adulthood?
What is one of the most important developmental tasks in late adulthood? Newman and Newman (2012) identify developmental tasks as areas of learning for most people in modern society. They associate the stage of later adulthood (60 to 75) with such tasks as accepting one’s life, redirecting energy toward new roles, promoting intellectual vigor and […]
What are the methods of measuring resistance?
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 […]
When a slab of dielectric medium is placed between plates of a parallel plate capacitor which is connected with a battery then the charge on plates in comparison with earlier charge?
When a slab of dielectric medium is placed between plates of a parallel plate capacitor which is connected with a battery then the charge on plates in comparison with earlier charge? Two identical capacitors are connected as shown in the figure. A dielectric slab is introduced between the plates of one of the capacitors so […]
Can an explosion trigger an earthquake?
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 happens to pressure if volume decreases in gas?
What happens to pressure if volume decreases in gas? Explanation: Gas particles exert pressure by colliding with the walls of their container. If you reduce the volume, you are effectively increasing the density of the particles and they will collide with the walls more frequently, leading to an increase in pressure. Why does the volume […]
