How much heat is needed to vaporize 10.00 grams of water at 100.0°c? the latent heat of vaporization of water is 2,259 j/g. a. 22.59 j b. 1,000 j c. 2,269 j d. 22,590 j

Answer : The correction option is, (d) 22,590 J

Solution : Given,

Mass of water = 10 gram

Latent heat of vaporization = 2259 J/g

As per question we conclude that,

In 1 gram of water the heat needed to vaporizes = 2259 J

In 10 gram of water the heat needed to vaporizes =

Therefore, the amount of heat needed to vaporize is, 22590 J

convex lenses are thicker at the middle. rays of light that pass through the lens are brought closer together (they converge). a convex lens is a converging lens. when parallel rays of light pass through a convex lens the refracted rays converge at one point called the principal focus.
