Calculate the number of calories given off by 300 grams of water cooling from 30C to 20C?
Water releases 80 calories per gram per degree Celsius. 80 * 300 * 10 = 240000 calories, or 240 kilocalories.
What is larger a Celsius degree or a Fahrenheit degree?
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.
The lowest degree number in celsius?
negative 273.15
What is the total number of calories of heat needed to raise to raise the temperature of the liquid water from 20 degrees Celsius to 30 degrees Celsius?
To calculate the total number of calories of heat needed, you can use the formula: Q = m * c * ΔT, where Q is the heat energy in calories, m is the mass of the water, c is the specific heat capacity of water (1 calorie/gram °C), and ΔT is the change in temperature. Assuming you have 100 grams of water, the calculation would be: Q = 100g * 1 cal/g°C * 10°C = 1000 calories.
What is the amount of energy needed to change the temp of a substance called?
The amount of energy needed to change the temperature of a substance is known as heat. It is measured in units such as calories or joules. It takes a specific amount of heat energy to raise the temperature of a substance by a certain number of degrees Celsius.
What is warmer -7 degree Celsius or -3.5 degree Celsius?
-3.5
What influences the number of calories needed in a persons diet?
The height, age, and weight of a person influences the number of calories needed. I'm not sure, but I think exercise may also be a factor.
What is the Fahrenheit to Celsius ratio?
1 Fahrenheit degree = 5/9 of one Celsius degrees 1 Celsius degree = 1.8 Fahrenheit degree There is no constant ratio between the °F and °C numbers for the same temperature, because their zeros are at different temperatures. A Celsius number less than -40° is colder than the same Fahrenheit number. A Celsius number more than -40° is warmer than the same Fahrenheit number. And -40° is the same actual temperature in both °F and °C.
How many degrees Celsius is equal to 1 degree 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 -17.22 degrees Celsius.
-11 degree celsius equals what degree 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 about 12.2 degrees Fahrenheit.
If it is 15 degree Fahrenheit what is the celsius degree?
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 -9.44 degrees Celsius.
Does the celsius sign go before or after the C?
The Celsius sign is the C; the little circley thing at the top is the degree sign and goes before the C
