During the first quarter of the year, a specific location in Aurora had an average air temperature of 35°C and a pressure of 0.998 atm. What is the direct distance between this place and La Trinidad if the city is elevated at a 45° angle to this location? The pressure in La Trinidad is assumed to be 0.834 atm. Every 1000 feet of vertical elevation, the temperature of the atmosphere drops by about 1.2 degrees Celsius. What is the average temperature in La Trinidad this time of year (in degrees Celsius)? Assume that the air is still and behaves like an ideal gas.

According to the Delaware River Port Authority, the total length of the Walt Whitman Bridge is nominally 11,982 feet. Assuming that the bridge was made entirely of steel, by how many meters does the bridge’s length change as its temperature rises from a winter temperature of 5°F to a summer temperature of 105 °F? Length change = _________meters. Be sure to first convert all lengths and temperatures to S.I. units
A plastic cup of negligible mass contains 0.280 kgkg of an unknown liquid at a temperature of 36.0 ∘C∘C. A 0.0270 kgkg mass of ice at a temperature of 0.0∘C∘C is added to the liquid, and when thermal equilibrium is reached the temperature of the combined substances is 14.0 ∘C∘C. Assuming no heat is exchanged with the surroundings, what is the specific heat capacity of the unknown liquid? Express your answer in joules per kilogram-kelvin.
After sitting out of a refrigerator for a while, a turkey at room temperature (72^\circ72∘F) is placed into an oven. The oven temperature is 315^\circ315∘F. Newton's Law of Heating explains that the temperature of the turkey will increase proportionally to the difference between the temperature of the turkey and the temperature of the oven, as given by the formula below: T=T_a+(T_0-T_a)e^{-kt}T=Ta+(T0−Ta)e−kt T_a=Ta= the temperature surrounding the objectT_0=T0= the initial temperature of the objectt=t= the time in hoursT=T= the temperature of the object after tt hoursk=k= decay constant The turkey reaches the temperature of 136^\circ136∘F after 2 hours. Using this information, find the value of kk, to the nearest thousandth. Use the resulting equation to determine the Fahrenheit temperature of the turkey, to the nearest degree, after 6 hours. Enter only the final temperature into the input box.
