\(5 \mathrm{~g}\) of steam at \(100^{\circ} \mathrm{C}\) is mixed with \(5 \mathrm{~g}\) of ice at \(0^{\circ} \mathrm{C}\). What is the final temperature of the mixture?
- A \(100^{\circ} \mathrm{C}\)
- B \(95^{\circ} \mathrm{C}\)
- C \(90^{\circ} \mathrm{C}\)
- D \(80^{\circ} \mathrm{C}\)
Answer & Solution
Correct Answer
(A) \(100^{\circ} \mathrm{C}\)
Step-by-step Solution
Detailed explanation
Given, mass of steam, \(m_\lambda=5 \mathrm{~g}\) Temperature of steam, \(T_s=100^{\circ} \mathrm{C}\) Mass of ice, \(m_i=5 \mathrm{~g}\) Temperature of ice, \(T_i=0^{\circ} \mathrm{C}\) Since, latent heat of vaporisation, \(l_v=540 \mathrm{cal} / \mathrm{g}\) Latent heat of…
