Question

some steam at hundred degree celsius is passed into 1.1 kg of water contained in a calorimeter of water equivalent 0.2 kg at 15 degree Celsius so that the temperature of the calorimeter and its contents rises to 80 degree Celsius what is the mass of steam condensing in kg

Answer 1

Let the mass of sream = x When it is passed through water it release heat and that heat is gained by water to increase its temp.. So, heat released =heat gained by water x×540 +x×1×(100-80) = 1.1×1×(80-15) + 0.02 ×1×(80-15) On solving this we get x= 0.13 kg

Answer 2

Answer:

The mass of the steam condensed in kg is 0.130 kg.

Explanation:

Given,

Steam at 100ºC is passed into 1.1 kg of water contained in a calorimeter of water equivalent 0.02 kg at 15ºC till the temperature of the calorimeter and its contents rises to 80ºC.

To find: The mass of the steam condensed in kg.

Solution:

Applying conservation of heat Energy,

Heat released by steam = heat gained by water and calorimeter

mL + m × S (100 – 80) = (1.1 + 0.02) × S × (80 – 15)

m × 540 + 20 m = 1.12 × 65

m = 0.130 kg.

Therefore, The mass of the steam condensed in kg is 0.130 kg.
