10.0 grams of water are heated during the preparation of a cup of coffee 1.0x 103 j of the heat are added to the water. which is initially at 20 c what is the final temperature of the coffee

The final temperature of the coffee is 43.9°C

Explanation:

To calculate the final temperature, we use the equation:

where,

q = heat released =

m = mass of water = 10.0 grams

C = specific heat capacity of water = 4.184 J/g°C

= final temperature = ?

= initial temperature = 20°C

Putting values in above equation, we get:

Hence, the final temperature of the coffee is 43.9°C
