A 30.0 g sample of aluminum is heated to 100°C before being placed in 225.0mL of water. The metal-water combination reaches a final temperature of 13°C. The specific heat capacity of aluminum is 9.2 x 10^2 J/kg°C. What was the initial temperature of the water? Please answer quick!!

The magnitude of the magnetic field at a certain distance from a long, straight conductor is represented by b. what is the magnitude of the magnetic field at twice the distance from the conductor? a. at twice the distance, the magnitude of the field is 4b. b. at twice the distance, the magnitude of the field is 2b. c. at twice the distance, the magnitude of the field is b/2.d. at twice the distance, the magnitude of the field is b/4.e. at twice the distance, the magnitude of the field remains equal to b.
