13. A closed bowl containing a mixture of equal amounts of water and ice at temperature 6 = 0 °C, when left in a room, the whole ice melts in time Ato = 160 min. Room temperature is 6, = 25 °C, specific heat of water is 4.2 kJ/(kg K) and specific latent heat of melting of ice is L = 320 %3D Sw = kJ/kg. If the bowl were further left in the room undisturbed, how long would it take to increase temperature of water in the bowl from 0 = 22 °C to 6 = 23 °C? 42 min %3D

Steady State Model

The steady-state model typically states that the entire universe is always enlarging, although it balances a fixed average density and matter that is being constantly generated to make new galaxies, star forms at a similar rate that the previous ones get indistinguishable due to the growing range and velocity of recession.
