MODULE 5 ASSIGNMENT
1. 300g of water is heated so that its temperature rises from 40°C to 84°C in 6minutes. Calculate the heat supplied per minute. (Specific heat capacity of water is 4200JKg-1K-1)
2. What mass of water at 100°C should be added to 23g of water at 30°C to make the. Temperature of the mixture 60°C
3. What is the quantity Oc heat that will be given out if a bar of brass of mass 200g is cooled from 68°C to 14°C (specific heat capacity Oc brass is 380JKg-1K-1)
