3.465 x 104 J are applied to equal masses of copper and aluminum. Which metal will reach a higher temperature (the specific heat capacity is 0.385 J g-1 K-1 for copper; 0.900 J g-1 K-1 for aluminum)? Would the same amount of joules bring an equal mass of water to a similar temperature?

1.) Two 100 g pieces of metal, one copper and one aluminum, that start at the same temperature are put in an oven for 2 minutes. When they are taken out of the oven, the copper feels warmer than the aluminum. This can be explained by the relative values of specific heat for the two metals. Copper must have a [ Select ] ["higher", "lower"] specific heat capacity than the aluminum, because [select one: higher heat capacity men a high...

J. Doe has an income of $60, which is divided between two goods: Xers (X) which costs $3 each, and Yers (Y), which costs $4 each. When prices and income are at these levels, Doe chooses the consumption bundle X = 12 and Y = 6.Suppose the price of Xer falls to $2, but simultaneously the price of Yer increases to $6. Is Doe better off, worse off, or exactly as well off as before? Explain your reasoning using a...
