A sample of aluminum, which has a specific heat capacity of 0.897·J·g−1°C−1, is put into a calorimeter (see sketch at right) that contains 250.0g of water. The aluminum sample starts off at 85.1°C and the temperature of the water starts off at 23.0°C. When the temperature of the water stops changing it's 25.8°C. The pressure remains constant at 1atm. Calculate the mass of the aluminum sample. Be sure your answer is rounded to 2 significant digits.

maybe the spark is gone, love is a weird emotion and there is a possibility he may have found somebody else.

what is the average time it took the car to travel 0.25 meters?

the answer is b because, investigating whether another species of moth also drinks tears might be interesting, but it would not directly explain why this species of moth does.

to explain why this species of moth drinks tears, the scientist could ask: "what nutrients that moths need are in elephant tears? "

the scientist could experiment with moth repellent or oter ways to keep the moths away, but that would not answer his original question.
