1:11 File Details CHEM 120 - Fund of Col Chem #3765 - Spring 2022 Heat=(grams of sample) (specific heat(AT) Heat is measured in "scientific calories." One scientific calorie can warm 1 gram of water by 1°C. Specific heat is a measure of insulating ability. The specific heat of water is 1.00 calorie/g °C. AT is the change in temperature (typically measured in degrees Celsius). 1) How many calories of heat are needed to warm 60.0 grams of water from 25°C to 55°C? Given: Heat - (grams)(specific heat)(AT) & the specific heat of water is 1.00 cal/g °C. Show set-up for all calculations. (answer: 1,800 calories) 2) What mass of water can be warmed from 20.0°C to boiling by the absorption of 28,400 calories? (answer: 355 grams) 3) What temperature change should be expected when 25.0 grams of water absorbs 1000 scientific calories of heat (equal to 1 dietary Calorie). (answer: AT= 40°C) 4) Find AT and the final temperature when 175 grams of water, initially at 22°C, absorbs 11,375 calories. 1. Heat of Fusion of Ice (answer: AT = 65°C, final T is 87°) The purpose of this experiment is to measure the number of calories needed to melt ice. This is known as the "heat of fusion" of ice.
