Frost can form on a surface when the humidity is sufficiently high and the surface temperature falls below freezing. What is the highest outdoor temperature at which frost can form on the inside of a single-glazed window if it is 60 degree F indoors? Assume a U value of 1 Btu/(h middot ft^2 middot degree F).

Solution

frost is formed on the inside single glazed window when the hot air on the inside window comes in contact with the chilled plane of glass outside.this phenomenon reduces the temperature of air on the inside window which causes frosting .if the outsidetemperature is more cold enough then there will be formation of interior frost.60^0 f is the safe temperature for the survival of living eings the expected temperature isaroun 27^0c
