The answer to your question is Q = 355.64 J

Explanation:

Data

Heat = Q = ?

Temperature 1 = T1 = 20°C

Temperature 2 = T2 = 37°C

mass = m = 5 g

Specific heat = Cp = 4.184 J/g°C

Formula

Q = mCp (T2 - T1)

-Substitution

Q = (5) (4.184) (37 - 20)

-Simplification

Q = (5) (4.184) (17)

-Result

Q = 355.64 J
