The heat of fusion (aka enthalpy of fusion) of ice at 0 °C is about 79.72 cal/g.
The specific heat of water in the range from 30 °C to 0 °C is about 1 cal/g/°C.
The total energy that must be removed is thus:
20.0 g x[(0-30)°C x 1 cal/g/°C - 79.72 cal/g] = -2184 cal
in other words you must remove 2184 cal to take 20.0 g of water from liquid at 30 30 °C to solid (ice) at 0 °C.
7 degrees Celsius is warmer than 3.5. The higher the number in degrees, the warmer it is!
Start by taking the number in Celsius and multiply it by 9. Then divide that number by 5, and then add 32. This is how you convert Celsius to Fahrenheit or use the equation F = (9/5)C + 32In this case, the answer is about 90.68 degrees Fahrenheit.
Start by taking the number in Celsius and multiply it by 9. Then divide that number by 5, and then add 32. This is how you convert Celsius to Fahrenheit or use the equation F = (9/5)C + 32In this case, the answer is about 275 degrees Fahrenheit.135 degrees Celsius = 275 degrees Fahrenheit.
Start by taking the number in Celsius and multiply it by 9. Then divide that number by 5, and then add 32. This is how you convert Celsius to Fahrenheit or use the equation F = (9/5)C + 32 In this case, the answer is 111.74 degrees Fahrenheit.
Start by taking the number in Celsius and multiply it by 9. Then divide that number by 5, and then add 32. This is how you convert Celsius to Fahrenheit or use the equation F = (9/5)C + 32In this case, the answer is about 66.2 degrees Fahrenheit.
Water releases 80 calories per gram per degree Celsius. 80 * 300 * 10 = 240000 calories, or 240 kilocalories.
A calorie is the amount of heat you need to raise the temperature of one gram of water by one degree Celsius. Assuming you are raising the temperature of the water from twenty degrees Celsius to ninety-nine degrees Celsius, it would take 20,000 calories. To calculate this, subtract 20 from 99. This is the amount of degrees you need to raise the temperature of the water by. Then multiply that number by 256, the amount of water in grams. You should get 20,244 calories. In significant digits, your answer should be 20,000 calories.
7 degrees Celsius is warmer than 3.5. The higher the number in degrees, the warmer it is!
Yes, -13 degrees Celsius is colder than -10 degrees Celsius. The lower the number in degrees Celsius, the colder the temperature.
No, -13 degrees Celsius is actually colder than -10 degrees Celsius. The larger the negative number, the lower the temperature.
Since Celsius degrees are larger than Fahrenheit degrees, above -40 degrees (where the scales coincide) any number in Celsius will be hotter than the corresponding number in Fahrenheit.
Start by taking the number in Fahrenheit and subtracting 32. Then divide the number by 9, and then multiply it by 5. This is how you convert Fahrenheit to Celsius or use the equation C = (F - 32) × 5/9In this case, the answer is about 47.22 degrees Celsius.
1 Degree of Celsius is larger. The number of degrees Fahrenheit between Water freezing (32) and boiling(212) is 180 degrees. The number of degrees Celsius is 100 degrees. So the Celsius degree has more value.
0 degrees Celsius is a colder temperature than 40 degrees Celsius. 0 degrees Celsius is the freezing level for water. Any positive number above 0 degrees Celsius is a warmer temperature.
16 Celsius = 61 Fahrenheit
