Step 1

Given:

Mass of ethylene glycol=10.2 g

Heat loss (q)=946 J

Final temperature=32.5oC

Specific heat capacity (c) of ethylene glycol=2.42 J/g.K

Step 2

To calculate initial temperature of ethylene glycol:

Consider an equation, where heat flow (q) of process is equal to change in enthalpy

Step 3

Calculating the initial temperature,
