A 0.500 kg aluminum pan on a stove is used to heat 0.250 liters of water from 20.0ºC to 80.0ºC. Part (1): Calculating specific heat capacity of brass1) Calculate the mass of water.2) Calculate the change in temperature of the metal cube.3) Calculate the change in temperature of water in the calorimeter.4) What is the amount of heat transferred into the water?5) How much is the heat released by the metal cube? Explain your reasoning.6) Calculate the specific heat capacity of the metal. This is the experimental value.7) Compare the calculated specific heat capacity with the theoretical specific heat capacity, using percent error. How much is the percent error?8) If the percent error is less than 10% what can you conclude? If the percent error is greater than 10% what can you conclude? Explain your answer.

waves moving from a fast medium to a slow medium will experience a reflection as light travels more slowly than red light. total internal reflection occurs when the critical angle is.

speed of light in vacuum is 300,000 km/s

speed of light in other mediums is given by the expression v = c/n, where c is the speed of light in vacuum and n is the refractive index of medium.

for the first medium v = 200,000 km/s

  so, refractive index of medium = 300000/200000 = 1.5

    1.5 refractive index is usually for glass. so first medium is glass.

for the second medium v = 250,00 km/s

so, refractive index of medium = 300000/250000 = 1.2

    1.2 refractive index is usually for water. so second medium is water.

for the third medium v = 0 km/s

so, refractive index of medium = 300000/0 = ∞

    ∞ refractive index is usually for opaque mediums. so third medium is opaque medium.
