a) Determine the mass of water vapor, initially at 130 ° C,needed to heat 200 g of distilled water in a 100 g glass container,to go from 20 ° C to 50 ° C.
The specific heat of water vapor is 2.01x103 J / kg ° C, thespecific heat of distilled water is 4.19x103 J / kg ° C, the latentheat of condensation of water vapor is 2.26x106 J / kg and theSpecific heat of the glass is 837 J / kg ° C
