Answer:

297.6 J

Step-by-step explanation:

Given that,

Mass, m = 4 grams

We need to find how much heat is absorbed when 4.0 grams of steam is heated from  120°C to 160°C.

We know that heat absorbed is given by :

Q=mc\Delta T

Where c is specific heat of water

Put all the values, we get :

Q=4\times 1.86\times (160-120)\\\\=297.6\ J

So, 297.6 J of heat is absorbed.
