Q=cm \Delta T \ \ \ \ \ \Rightarrow \ \ \ c=\frac{Q}{m\Delta T}\\\\
Q=183J\\
m=18,5g\\
\Delta T=78,6^{o}C-35^{o}C=43,6^{o}C\\\\
c=\frac{183J}{18,5g*43,6^{o}C}\approx0,227\frac{J}{g^{o}C}

Answer:

0.227 J/g°C

Explanation:

Specific heat is the heat change by one gram of substance if it is subjected to change of 1 degree celsius.

The relation between specific heat and mass and change in temperature is:

Q = heat change = mass X specific heat X change in temperature.

Given:

Q = 183 J

Mass = 18.5g

increase in temperature = 78.6-35 = 43.6 °C

Putting values

183 = 18.5X specific heat X 43.6

Specific heat = \frac{183}{18.5X43.6}= 0.227\frac{J}{g^{0}C}

Mass defect is associated with: nuclear fusion nuclear fission radioactive decay mass lost by nuclear collisions
Kay [80]
I would say mass lost by nuclear collisions. The mass defect is the mass difference between the mass of an atomic nucleus and the sum of the mass of its constituent particles. It equals the energy given off in the formation of the nucleus.
