Answer to Question #272864 in General Chemistry for lei

Question

One gram of H₂O at -50 ⁰C was heated and become 110 ⁰C. Cp ice = 0.5 cal/g-K, Cp steam = 0.48 cal/g-K

At what temperature in degC involved the latent of vaporization?

How much heat in J was involved from the start up to right before melting?

How much heat in J was involved from right upon melting to right before boiling?

How much heat in J was involved from right before boiling up to the end of heating?

Answer 1

Temperature in degC involved the latent of vaporization=39.4°C
