How much heat is needed to raise the temperature of 6g of water by 15°c

Explanation:

Firstly, we need the specific heat capacity of water which is typically around 4200J/kg (if the mass is in kg) or 4.2 J/g ( if mass is in g)

The formula for the heat energy needed is

E=mct

Where E is the heat energy, m is the mass of water, c is the specific heat capacity and t is the change in the temperature.

E= 6 x 4.2 x 15

= 378 J

Hope this helps!!!

Feel free to ask any follow up questions!

need to see circuit to get time constant
