Calorimetry: Two experimental runs are performed to determine the calorimetric properties of an alcohol which has a melting point of -10°C. In the first run, a 200-g cube of frozen alcohol, at the melting point, is added to 300 g of water at 20°C in a styrofoam container. When thermal equilibrium is reached, the alcohol-water solution is at a temperature of 5°C. In the second run, an identical cube of alcohol is added to 500 g of water at 20°C and the temperature at thermal equilibrium is 10°C. The specific heat capacity of water is 4190 J/kg ? K. Assume no heat is exchanged with the styrofoam container and the surroundings. What is the specific heat capacity of the alcohol?
A. 1700 J/kg ? K B. 1900 J/kg ? K C. 2100 J/kg ? K D. 2300 J/kg ? K E. 2500 J/kg ? K
Uncertainty Principle Using Energy and Time: The excited state of a certain atom is 3.2 eV ± 0.21 eV. (h = 6.626 × 10-34 J ? s, 1 eV = 1.60 × 10-19 J)(a) What is the average lifetime of this state, in femtoseconds?(b) If the excited energy were doubled (to 6.4 eV ± 0.21 eV), how would the lifetime be affected?
What will be an ideal response?
A proposed explanation for gamma-ray bursters is:
A) hypernova-making black holes and bi-polar jets. B) coalescence of a neutron star binary. C) collisions between two white dwarfs. D) Both A and B are possible. E) All three are possible.
