☆回 凸 rris - Specific Heat Practice Last edit.. ew Insert Format Tools Add-ons Help Accessibility + BIUA 100% Normal text New Rocker 22 4. A box of Penguin Flakes® Cereal ™ has 540 Calories. If all of these calories are used to hea bathtub of water (c 1.00 cal/g°C) by 10.0°C, how many kilograms of water are in the bathtul 5. The heat from a candy bar's Calories can raise the temperature of a 4.50 kg bucket of water f to 68°C. How many Calories are in the candy bar? 6. A 45.2 gram sample of an unknown metal has 25,533 Joules of heat added to it. If its tempera changes from 4.00°C to 733°C, what is the metal's specific heat capacity? 7. (challenge problem) Gold has a specific heat of 01129 J/g°C. A scientist has been given a gram coin and has been told it is pure gold. When she adds 412.8J of heat to the coin, its tem rises from 72°F to 144°F. Is the coin actually made of gold?
