Question

.1. A 2.50 kg block of ice at 0°C is added to a picnic cooler. How much heat (in kcal) will the ice remove as it melts to water at 0°C? 

2. A 300.0 g pot of water at room temperature (25.0°C) is placed on a stove. How much heat (in kcal) is required to change this water to steam at 100.0°C? 

3. Spent steam from an electric generating plant leaves the turbines at 110.0°C and is cooled to 95.0°C liquid water by water from a cooling tower in a heat exchanger. How much heat (in kcal) is removed by the cooling tower water for each kg of spent steam? 

4.A heat engine converts 250.0 cal from a supply of 500.0 cal into work. How much mechanical work (in J) was done? 

5. Take a metal with a specific heat of 0.047 kcal/kgCº, a melting point of 255.0°C, and a heat of fusion of 4.3 kcal/kg. How much heat (in kcal) must be provided to melt a 125.0 kg sample of the metal with an initial temperature of 35.0°C? Enter answer

Answer 1

Solving the problem realted to specific heat of ice, steam & water and also Latent Heat Of Fusion & Vapourisation .
