Question

25.
Two spheres have the same mass but are made of materials with their specific heats in the ratio 1:2.
Then ratio of their water equivalents is (HW)
1) 1:2
2) 2:1
3) 1:4
44:1​

Answer 1

Answer:

the answer is 1:2 bro and I am follow you

Answer 2

Then ratio of their water equivalents is :-  (1) 1:2

- It is given that :

Mass of spheres, m₁ = m₂ = m

Ratio of specific heats, c₁ : c₂ = 1 : 2

where m = mass of each sphere and c₁, c₂ are the specific heats of spheres 1 and 2 respectively.

- We know that the water equivalent is given by :

Water equivalent = Mass × Specific Heat

⇒w₁ / w₂ = m₁c₁ / m₂c₂

⇒w₁ / w₂ = c₁ / c₂

⇒w₁ / w₂ = 1 / 2

⇒w₁ : w₂ = 1 : 2

- Hence, the correct answer is option (1).
