A Boeing 767-400ER traveling from Atalanta, Georgia (ATL) to Paris, France travels an average distance of 4394 miles. When carrying 283 passengers on this route, the efficiency recorded by the aircraft approaches 64.2 miles/gallon per passenger. What is the minimum quantity of fuel that 1.00gal = 3.78L?

You will find the final temperature when 5.00 grams of aluminum at 425℃ is placed in 50.0 grams of water at 19.5℃. Aluminum has a specific heat capacity of 0.900 J/g ℃. And water has a specific heat capacity of 4.184 J/g℃. Now set –q(hot) = q(cold) and solve for the final temperature (as done in class) and then give the calculator answer for the final temperature! (Give 7 digits). Select one: a. 8.755643 ℃ b. 26.35996 ℃ c. 12.39981 ℃ d. 28.64197 ℃ e. 29.70363 ℃ f. 10.58574 ℃ g. 30.47036 ℃ h. none of these i. 26.81358 ℃ j. 28.03884 ℃

A lab you will soon perform is on specific heat.  What is specific heat?  The specific heat of copper is 0.385 J/goC.  Determine the energy required to increase the temperature of 250.0 g of copper from 42oC to 150oC.  Here’s your formula:  Q = mc∆T. m is mass, c is specific heat, T is temperature and Q is heat.

An iron kettle weighing 1.43 kg contains 2.84 kg of water at 25.3°C. The kettle and water are heated to 80.6°C. How many joules of energy are absorbed by the water and by the kettle? i x 10 i J are absorbed by the water i x 10 i J are absorbed by the kettle

Convert 52.7 Cal  to  kJ

If 227.9 Joules of heat are added to 25.96 grams of a liquid, raising the temperature of the liquid from 27°C to 33.8°C, what is the specific heat capacity of the liquid with units of J/g•°C? Report your answer with 3 significant figures.
