Question

When 100g of steam is added to 0.4 kg of water at 30 degree Celsius , the resultant temperature of the mixture is

Answer 1

Answer:

I AM ASSUMING THAT STEAM IS AT 100 DEGREE CELCIUS...

Explanation:

TEMPERATURE OF STEAM = 100 *C

TEMPERATURE OF WATER = 30*C

MASS OF WATER = 0.4 Kg

MASS OF STEAM = 0.1 Kg

ACCORDING TO FORMULA

m1 c1 T1 = m2 c2 T2

0.1 x 2.1 x [100*C - T] = 0.4 x 4.2 X [ 30*C + T]

100 - T = 240 + 8T

140 / 9 = T

=> 410 / 9 DEGREE CELCIUS
