WebFeb 14, 2024 · As water cools it will reach 32°F (or 0° C) is will stay at that temperature until all the water freezes (Figure 7.12). To convert 1 gram of ice at 0° C to 1 gram of water at 0° C requires 80 calories. To convert 1 gram of water at 100° C to 1 gram of steam at 100° C requires 540 calories. WebThe mass is still 18.0 grams but the specific heat now, since we have liquid water, we need to use the specific heat of liquid water, which is 4.18 joules per gram degrees Celsius. And for the change in temperature, the final temperature is 100. So 100 minus zero gives us +100 degrees Celsius. So grams cancel out, degrees Celsius cancels out ...
