Question

How much steam at 1000C is to be passed into water of mass 100gm at 200C to

raise its temperature by 5

0 C? (Latent heat of steam is 540 ca/gm and specific

heat of water is 1 cal/gmc0
6)​

Answer 1

Answer:

100 g at 20° C to raise its temperature 5° C? (Latent heat of steam is 540 cal/g and specific heat of water is 1 cal/g° C). 2.

Answer 2

Given : steam @ 100 degree Celsius , let it be X amount. water of 100 gm @ 20 degree Celsius ; ∆t = 5 degree

final temperature = 25 degree Celsius

(The amount of heat energy lost by steam) =( heat energy gained by water )

so , from Q = ms∆t

first to convert steam @ 100 degree Celsius into water @100 degree Celsius it has to loose latent heat i.e., 540 Ca/gm.

X x 540 + X x 1 cal/gm x (100 - 25) = 100 x 1 cal/gm x ( 25 - 20 )

=> X (540 + 75) = 500gm

=> X = 0.813 gm
