Answer:
419.76 J absorbed
Step-by-step explanation:
In thermodynamics, the specific heat of a substance is the amount of energy required to raise 1 gram of the substance by one degree Celsius. The formula involving specific heat is Q = mCΔT, where Q is the amount of heat gained (absorbed) or lost (released) by the substance, m is the mass of the substance, C is the specific heat, and ΔT is the change in temperature.
We are already provided all the information we need to solve for Q, so we can plug the appropriate values into the equation:
- Q = mCΔT
- Q = (95.4 g)(0.44 J/g*⁰C)(32⁰C - 22⁰C)
- Q = (41.976 J/⁰C)(10⁰C)
- Q = 419.76 J
The last step of the problem is determining whether energy is absorbed or released. We calculated Q to be a positive value, which means that energy is absorbed. We also know energy is absorbed because the temperature of the nickel increased, meaning that it gained thermal energy.
