A coffee machine makes use of 100°C steam to warm up 0.18 kg coffee at 14°C to 85°C. What is the mass of steam needed in g? Assume that coffee has the same thermal properties as water, that all heat from steam will be used to raise the temperature of the coffee, and that steam used becomes part of coffee
