A chemist carefully measures the amount of heat needed to raise the temperature of a 823.0g sample of a pure substance from 0.1°C to 17.8°C. The experiment shows that 13.2kJ of heat are needed. What can the chemist report for the specific heat capacity of the substance? Be sure your answer has the correct number of significant digits.
In the laboratory a student uses a "coffee cup" calorimeter to determine the specific heat of a metal.She heats 19.2 grams of magnesium to 98.96°C and then drops it into a cup containing 77.8 grams of water at 22.66°C. She measures the final temperature to be 27.15°C.Assuming that all of the heat is transferred to the water, she calculates the specific heat of magnesium to be ________ J/g°C.
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!
