Q. No.On a new scale of temperature, which is linear and called the \(\text{W}\) scale, the freezing and boiling points of water are \(39^\circ ~\text{W}\) and \(239^\circ ~\text{W}\) respectively. What will be the temperature on the new scale corresponding to a temperature of \(39^\circ ~\text{C}\) on the Celsius scale?
1. \(78^\circ ~\text{W}\)
2. \(117^\circ ~\text{W}\)
3. \(200^\circ ~\text{W}\)
4. \(139^\circ ~\text{W}\)

A \(100\) g of iron nail is hit by a \(1.5\) kg hammer striking at a velocity of \(60\) ms–1. What will be the rise in the temperature of the nail if one-fourth of the energy of the hammer goes into heating the nail?
[Specific heat capacity of iron = \(0.42\) Jg–1 °C–1]
[Specific heat capacity of iron = \(0.42\) Jg–1 °C–1]
