Answer #1

The relation between heat absorbed, mass of substance, specific heat capacity and temperature change is given by,

q=mcT,

where, q is heat absorbed, m is mass pf the substance, c is specific heat capacity  T is difference between initial and final temperatures i.e., (Tf - Ti)

Given, q is 367 J, m is 12.8 gm, c is 0.385 J/g°C, Ti is 35.0°C, so we have to find Tf.

Putting all data in the equation,

367 = 12.8 × 0.385 × (Tf - 35)

Tf - 35 = 367/4.928 = 74.47

So, Tf = 74.47 + 35 = 109.47 °C = 109 °C
