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?
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?
How does idea of something being quantized relate to the lab we did this week. Why do elements emit very specific colors of light when heated?
A box that is 1.00 m long measured from left to right has a sliding partition that separates it into two compartments. The left compartment contains 30 particles, the right one contains 40 particles, and initially the partition is 0.750 m from the left wall of the box. If the partition is allowed to move […]

In the figure below, a man is trying to get his car out of mud on the shoulder of a road. He ties one end of a rope tightly around the front bumper and the other end tightly around a utility pole a distance d away. He then pushes sideways on the rope at its […]
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 =
