What is the mass of a piece of zinc that absorbs 1576 calories of heat and increased its temperature by 8.7 °C (specific heat of zinc is 0.39 cal/gºC). SHOW YOUR WORK *

m = 476.5[g].

Explanation:

In order to solve this problem, we must use the following equation of thermal energy.

where:

Q = heat energy = 1576 [cal]

Cp = specific heat = 0.39 [cal/g*°C]

T_final = final temperature [°C]

T_initial = initial temperature [°C]

m = mass of the piece of zinc [g]

We must keep in mind that the difference of the final temperature minus the initial temperature results in the increase in temperature.

Now replacing:

answer: a ball

explanation: because it will bounce

i think it’s a. this is because if they measured the mass of something with a mass of 150g, then their final answer would have to be approximately 150g. though all of their answers are almost 150, rosa and tran have the closest answers (or the exact answer) to the accurate one.
