How much heat is required to convert 422 g of liquid h2o at 23.5 °c into steam at 150 °c?
Misha Larkins [42]
Heat is given by multiplying the specific heat capacity of a substance by mass and the change in temperature. The heat capacity of water is Approximately 4184 J/K/C.
Therefore, heat = mc0 mass in kg
                         = (422/1000) × 4184 × (100-23.5)
                         = 135072.072 J
Latent heat of vaporization is 2260 kJ/kg
Thus the heat will be 0.422 × 2260000 = 953720 J
Heat to raise steam from 100 to 150 
    2000 × 0.422 ×50 = 42200 J
Thus the heat required is (135072.072 + 953720 + 42200) = 1330992.07 Joules or 1330 kilo joules

Natasha2012 [34]

Answer:

A. the​ bond's yield to maturity is equal to its coupon rate.

Explanation:

The coupon rate is that amount of bond measured on the loan amount whereas the maturity yield is the rate held up to the settlement date and the investment arise up to the maturity date.

Since the bond is currently trading at its face value that means the bond price is equal to the face or par value

So, the appropriate option is A.
