Q. No.Steam at \(100~^{\circ}\text{C}\) is passed into \(20~\text{g}\) of water at \(10~^{\circ}\text{C}.\) When water acquires a temperature of \(80~^{\circ}\text{C},\) the mass of water present will be:
[Take specific heat of water \(= 1~\text{cal g}^{-1}~^\circ\text{C}^{-1}\) and latent heat of steam \(= 540~\text{cal g}^{-1}\)]
[Take specific heat of water \(= 1~\text{cal g}^{-1}~^\circ\text{C}^{-1}\) and latent heat of steam \(= 540~\text{cal g}^{-1}\)]

If the cold junction of a thermocouple is kept at \(0^{\circ}\text{C}\) and the hot junction is kept at \(T^{\circ}\text{C}\), then the relation between neutral temperature \((T_{n})\) and temperature of inversion \((T_{i})\) is:
1. \(T_n = \frac{T_i}{2}\)
2. \(T_n = 2T_i\)
3. \(T_n = T_i-T\)
4. \(T_n = T_i+T\)
1. \(T_n = \frac{T_i}{2}\)
2. \(T_n = 2T_i\)
3. \(T_n = T_i-T\)
4. \(T_n = T_i+T\)
