Question

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

Answer:

do u like fishing

Explanation:

because i do

Answer 2

Answer:

23.2 C

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 ? )
