Question 8 (1 point)

A lead sinker is used in fishing to weight a fishing line down. If 149.4 J of heat energy
J
was added to a lead sinker with a mass of 50 g. What is the total temperature change
for the lead sinker? Assume the specific heat (c) of lead is 0.129 J/gºC.
888

Answer 1

23.2 C

Step-by-step explanation:

By looking at the dimension of specific heat ( J/g-C) , you can compute these type of questions:

149.4 J / ( .129 J / g-C * 50 g) = 23.2 C

(see how dimensions g and J cancel out and you are left with C ? )
