Given the following specific heats, which would require the greatest amount of heat energy to increase its temperature by 50C?
A) one gram of ammonia, 4.70 J/(gC)
B) Two grams of water, 4.184 J/(gC)
C) Six grams of aluminum, 0.90 J/(gC)
D) Twenty grams of silver, 0.24 J/(gC)
E) All of the above require the same amount of heat energy.
Question 2
Gravity on the moon is only 1/6 as strong as gravity on the earth. What is the mass of a 10 kg object on the moon and on the earth?
A) A 10 kg object weighs 10 kg on Earth and 10/6 = 1.67 kg on the moon.
B) The mass of an object is indirectly proportional to the mass of the planet on which it is located. Therefore, a 10 kg object weighs 10/6 = 1.67 kg on Earth and 10 kg on the moon.
C) The mass of a 10 kg object anywhere is 10 kg.
D) The mass of a 10 kg object on Earth is 22 pounds, while on the moon it is 3.7 pounds.
E) The 10 kg object weighs 60 kg on the moon.
