## Main Question or Discussion Point

**Newton's Law of Cooling**

Time Required to Cool (or heat) an Object [Also known as Newton's Law of Cooling]

**t=mCp(Ts-Tf)/Q**

Where;

Q is the heat added (or being removed) from the object in watts

m is the mass (weight) of the object in Kg

Cp is the Specific heat of the object material in J/Kg C

t is the time required to cool down (or heat up) the object in seconds

Ts is the starting temperature in C

Tf is the final temperature in C

Here is what i am entering:

Q - 1700 W

m - 500 KG

Cp - ??????

Ts - 1 degC

Tf - 67 degC

But what should i enter for the 'Specific heat of the object material in

**J/Kg C**'?

The Object is Mercury.

Thank you
