The specific heat capacity of aluminum is about twice that of iron. consider two blocks of equal mass, one made of aluminum and the other one made of iron, initially in thermal equilibrium.
heat is added to each block at the same constant rate until it reaches a temperature of 500 k. which of the following statements is true?
a. the iron takes less time than the aluminum to reach the final temperature.
b. the aluminum takes less time than the iron to reach the final temperature.
c. the two blocks take the same amount of time to reach the final temperature.

Neptune is the eighth planet from the sun. it was the first planet to get its existence predicted by  mathematical calculations  before it was actually seen through a telescope on sept. 23, 1846. irregularities in the orbit of  uranus  led french astronomer alexis bouvard to suggest that the gravitational pull from another celestial body might be responsible. german astronomer johann galle then relied on subsequent calculations to   spot neptune via telescope. previously, astronomer galileo galilei sketched the planet, but he mistook it for a star due to its slow motion. in accordance with all the other planets seen in the sky, this new world was given a name from greek and roman mythology — neptune, the roman god of the sea.
