Calorimetry lab gizmo answers activity c


Activity C (continued from previous page) 3. Calculate: Use the Gizmo to mix 200 g of granite at 100 °C with 1,000 g of water

Answer

specific heat capacity of water = 4.18 J/g CC °C ( have to learn for this ) Heat energy needed to change the water temperature Q = m . c . Delta T Q = (3000g)   . (4.18 J/g °C) . ( 0.45 °C) Q = 5643 J For mass of granite DeltaT = 80°C – 20.45 °C Rightarrow 59.55 °C Q = m . c . Delta T 5643 = m . (0.79 J/g °C) . (59.55 °C) 5643 = m . 47.04 m = 112 g therefore , mass of granite is 112 g Here is your answer. Thank you. Please Thumbs up.
