Question

What is the energy needed to raise 2.004g of water from 89.0°C to 139.0°C?

2 Answer

  • Answer:

    The answer to your question is E = 419.435 J

    Explanation:

    Data

    Mass = m = 2.004 g

    Temperature 1 = T1 = 89°C

    Temperature 2 = T2 = 139°C

    Specific heat  of water = Cp = 4.186 J/g°C

    Energy = E = ?

    Formula

    E = mCp(T2 - T1)

    Substitution

    E = (2.004)(4.186)(139 - 89)

    Simplification and result

    E = 8.3887(50)

    E = 419.435 J
