Answer:

The answer to your question is Q = 2093 J

Explanation:

Data

Energy = Q = ?

mass = 20 g

Temperature 1 = 25°C

Temperature 2 = 50°C

Specific heat = Cp = 4.186 J/g°C

Formula

Energy = Q = mCp(Temperature 2 - Temperature 1)

Substitution

               Q = (20)(4.186)(50 - 25)

Simplification

               Q = (20)(4.186)(25)

Result

              Q = 2093 J
