A 0.075 kg ice cube at 0 degree C is dropped into an insulated Styrofoam cup holding 0.33 kg of water at 25.0 degree C. Calculate the final temperature of the system, neglecting the heat loss to the cup and the Outside. The specific heal of water is 4.2 kJ/kg0 degree C and the latent […]
Consider the expansion of 60.0 moles of a monatomic ideal gas along processes 1 and 2 in the figure. On process 1 the gas is heated at constant volume from an initial pressure of 106 kPa to a final pressure of 212 kPa . On process 2 the gas expands at constant pressure from an […]
Part 1: A New allele appears in crawfish population. Describe one factor that would most likely cause the frequency of the new allele to increase over time? Part 2: Suppose new mutation creates an allele that prevents juvenile crawfish from developing into adults. Describe how the future of the new allele in the population would be […]
Fats in the diet have satiety value They stay in stomach longer so we feel fuller longer. Fats provide protective coatings on the body surfaces to help prevent dehydration. Lipids – 2 What are the major categories of lipids found in humans?
o meet energy regulations, the coefficient of performance of cooling of a refrigerator that operates on a Carnot cycle must be 4.00. At what rate is this refrigerator expelling thermal energy into the kitchen if it consumes electrical energy at a rate of 245 W ? dQdt =
i was needing help to answer this one please. Here are the questions. A12: Lunar and Solar Eclipses Question 1: Why is an eclipse (lunar in this case) not possible at this time? Question 2: What is the phase of the Moon during a solar eclipse? Hint: Zoom in for a closer view of the […]
Mrs Chan is found lying at the bottom of her stairs by her daughter at 09:00 on 14/06/2016. Mrs Chan is dressed in a nightgown; the last thing she remembers is rushing to the toilet at about 10pm. She has no memory of falling, she recalls “waking up” on the floor feeling cold because she […]

On process 3 the gas expands at constant pressure from initial volume 1.00 m^3 to a final volume of 3.00 m^3. On process 4 the gas is heated at constant volume from an initial pressure of 106 kPa to a final pressure of 212 kPa .
What is the purpose of calibrating the torsion balance? Can you determine the Coulomb constant without calibrating the balance? Why?Why do electrostatic experiments not work properly on humid environment?
