Chapter 1, Problem 1.30E

1-86 The specific heats of some elements at 25oC are as follows: aluminum = 0.215 cal/g · oC; carbon (graphite) = 0.170 caI/g oC; iron = 0.107 cal/g mercury = 0.033 1 caI/g oC. (a) Which element would require the smallest amount of heat to raise the temperature of 100 g of the element by 10oC? (b) If the same amount of heat needed to raise the temperature of 1 g of aluminum by 25oC were applied to 1 g of mercury, by how many degrees would its temperature be raised? (c) If a certain amount of heat is used to raise the temperature of 1.6 g of iron by 10oC, the temperature of 1 g of which element would also be raised by 10oC, using the same amount of heat?

a 43g of chocolate has 2.10 x 102 calories. convert this energy to units of joules

Give the derived SI units for each of the following quantitiesin base SI units:(a) acceleration = distance/time2(b) force = mass x acceleration(c) work = force x distance(d) pressure = force/area(e) power = work/time(f) velocity = distance/time(g) energy = mass x (velocity)2

A sheet of gold weighing  8.6g and at a temperature of 14.9C  is placed flat on a sheet of iron weighing 19.6g and at a temperature of 58.9C . What is the final temperature of the combined metals? Assume that no heat is lost to the surroundings. Be sure your answer has the correct number of significant digits.
