1.0 A mass of ice at -7 °C is needed to cool 114 kg of vegetables (Cp = 3.35 KJ /kg.K )in a bunker for 24 hours . The initial temperature of the vegetables is assumed to be 29 °C . It is also assumed that the average temperature in the bunker is 7°C within the 24 - hour period . If the heat gained per hour in the bunker is 25% of the heat removed to the vegetables from 30 °C to 8°C, what would be the required mass of ice ?
