1. How much heat is needed to bring 8.9 g H₂O at 4°C to a boil? Hint: You may need to look up the boiling point of water. MAT SH : Q = 8-99 × 960, WATER BOILS AT 100°C :, AT (100-4)= 96°C =859-4 cal 2. What is a calorie? How are the science calorie and the food calorie different? 3. If burning 1 gram of cornflake (in a calorimeter) caused the temperature of 23.0°C water (100 mL) to climb to 68.4°C. How many food calories (Calories) are there in a 100 g bowl of cornflakes cereal without milk? Density of water =1.00g/ml :. Mass of water = 100mx 1.000 ML Floog XI cal -(MA+SH) metal = (M.AT.SH) water Smetal= -(m.AT.SH) water (M.AT.) metal SHmetal = -4540 cal Ig Cornflake Releases 4540 ca 14540 cal = 454000 cal loog Cornflake Releases 4. Re-arrange the following equation to solve for SHmetal454 Real - (m.AT-SH)metal = (m-AT-SH)water G-MAT SH - 100g x (68.4-2300 & 100 cal A metal AND ATwater ARE ARE) Different 5. Define the specific heat capacity of water? What units are used for this value?
