Step 3: Record the mass of the cup and water. Answer to the nearest 0.1 g.
Calculate the mass of the water.
Step 4: Record the mass of the object. Answer to the nearest 0.1 g.
Step 9: What is the starting temperature in the cup? Answer to the nearest 0.1 degree.
Step 9: What is the highest temperature in the cup? Answer to the nearest 0.1 degree.
Step 10: Calculate the heat gained by the water. Round your answer to the nearest whole number.
Step 10: Calculate the specific heat of your unknown. Round your answer to 2 after the decimal point.
If 200. grams of water is to be heated from 24.0°C to 100.0°C to make a cup of tea, how much heat must be added? The specific heat of water is 4.18 J/g∙°C. Round your answer to the nearest whole number. Do NOT include units in your answer.
A block of aluminum weighing 140. g is cooled from 98.4°C to 62.2°C with the release of 1080 joules of heat. From this data, calculate the specific heat of aluminum. Round your answer to two after the decimal. Do NOT include units in your answer.
