A cube of iron (Cp = 0.450 J/g•°C) with a mass of 55.8 g is heated from 25.0°C to 49.0°C. How much heat is required for this process? Round your answer to three significant figures.Use the formula q = mCT. J

A sample of tin (Cp = 0.227 J/g•°C) is placed in a freezer. Its temperature decreases from 15.0°C to –10.0°C as it releases 543 J of energy. What is the mass of the sample? Round your answer to three significant figures.Use the formula q = mCT. g

A 95.0 g sample of copper (c = 0.20 J/°C·g) is heated to 82.4°C and then placed in a container of water (c = 4.18 J/°C·g) at 22.0°C. The final temperature of the water and the copper is 25.1°C. What was the mass of the water in the original container? Assume that all heat lost by the copper is gained by the water. Use the formulas below to help in your problem-solving.-q = q-cmT = cmT0.246 g HO4.73 g HO84.0 g HO36,700 g HO
