A sample of aluminum, which has a specific heat capacity of , is put into a calorimeter (see sketch at right) that contains of water. The temperature of the water starts off at . When the temperature of the water stops changing it's . The pressure remains constant at . Calculate the initial temperature of the aluminum sample. Be sure your answer is rounded to the correct number of significant digits.

answer

i think the answer is a) as air pressure in an area increases, the density of the gas particles in that area decreases.

hope it

space exploration has led to the development and technological improvement of many everyday items. (if this answer is wrong i will find the right answer) : )

thats how its supposed to be

a pan containing water is placed in a positio n where it is exposed to a 10 mile per hour wind. the pan contains a uniform depth of 1.27 cm of water, is quite wide, and has a length of 2.44 m in the wind direction. the water in the pan is at a constant temperature of 15.5 °c.
