QUANTITY OF HEAT
Question on quantity of heat:
What mass of steam initially at 130°C is needed to warm 200g of water in glass container of mass 100g from 20°C to 50°C if:
Specific heat capacity of steam = 200J/kg/K.
Specific heat capacity of water = 4200J/kg/K.
Specific latent heat of vaporization if water= 2.26×10^6 J/Kg.
Specific heat capacity of glass = 840 J/kg/K.
