Can you show how number 4 is done
How many calories are needed to heat 12.00 grams of ice at -20.0°C to liquid water at 100.0°L? H vaporization = 540 cal /g Cice = C water = C steam = H fusion = 0.50 cal/g°C 1.00 cal/ g°C 0.48 cal/g°C 80.0 cal/g How many joules are needed to heat 25.0 grams of Freon from a liquid at -165°C to a vapor at 19.6°C? Note the melting point for Freon is -181°C and the boiling point is-81.4°C. 2. C Freon as a gas C Freon as a C Freon as a H fusion for H vaporization for Freon = liquid = 1.96 j/g°C = 0.660 j/g°C solid = Freon = 0.825 j/g°C 21 j/g 148 j/g 3. How much heat is absorbed when 11.2 grams of graphite is heated from 22.0 °C to 55.0°C if the specific heat of graphite is 0.170 cal/ g°C? 4. Determine the specific heat of a metal if 45.00 grams of the metal was placed in water at 98.0°C for 10.00 minutes and then placed in 112.40 grams of water at 16.0 °C. After the metal was placed in the water, the temperature of the metal-water mixture became 19.8°C. The specific heat of water is 1.00 cal / gram °C. If a sample of aluminum metal at 100.0°C is placed into 54.4 grams of water at 17.7°C and the water temperature rises to 23.0°C, calculate the mass of the aluminum sample. The specific heat of aluminum is 0.215 cal /g°C and the specific heat of water is 1.00 cal/ g°C. 5. nlaced into 88.7 grams of water at 20.0°C, calculate the
