The discussion centers on calculating the time required to raise the temperature of cookie dough from 25°C to 145°C. The energy required for this temperature change is calculated using the formula E = m * specific heat * (final temperature - initial temperature), resulting in E = 4,176 Joules for 0.012 kg of cookie dough with a specific heat of 2,900 J/kg°C. However, the discussion highlights the need for additional information, such as the heat source's power output, to determine the time needed for this temperature increase.

You need more information. Please post the complete question, along with some attempt at a solution.dannie7 said:im trying to work out time it takes to raise the temperature of cookie dough from 25 celsius to 145 celsius.
E=m*spec heat *(145-25)
I have E=.012*2900*(120)= 4176j,
how do I work out the time it takes. thanks in advance
