How many calories in 390 kcal?
"calories" (lowercase C) and "kilocalories" or "kcal" are interchangeable words. 1 Calorie (uppercase C) = 1000 calories (lowercase C) = 1 kilocalorie So, 390 kcal is equal to 390 calories as well.
How many kilocalories of heat are required to raise the temperature of 225g of aluminum form 20 degrees c?
The specific heat capacity of aluminum is 0.897 J/g°C. To convert this to kcal/g°C, we divide by 4.184 to get 0.214 kcal/g°C. Therefore, the total kilocalories of heat required to raise the temperature of 225g of aluminum from 20°C would be 225g * 20°C * 0.214 kcal/g°C = 966 kcal.
How many kilocalories of heat would be needed to melt 0.12kg of ice at 0 degrees c and increase the temperature to 25 degrees c?
To calculate the total kilocalories needed, first, you need to melt the ice. The latent heat of fusion for ice is approximately 80 kcal/kg, so melting 0.12 kg of ice requires 0.12 kg × 80 kcal/kg = 9.6 kcal. After melting, you need to raise the temperature of the resulting water from 0°C to 25°C. The specific heat of water is about 1 kcal/kg°C, so heating 0.12 kg of water by 25°C requires 0.12 kg × 25 kcal/kg°C = 3 kcal. Therefore, the total heat needed is 9.6 kcal + 3 kcal = 12.6 kcal.
How many kcal's are in one pound?
Hi The answer to your question is there is 3500 kcal in one pound!
If you burned 60 calories how many kcal did you burned?
1000 calories in one kcal so 1000 is to 1 as x is to 60 = .06 kcal
How many fat are in 110kcal?
To determine how many grams of fat are in 110 kcal, we need to know that fat provides 9 kcal per gram. Dividing 110 kcal by 9 kcal/gram gives approximately 12.22 grams of fat. Therefore, 110 kcal contains about 12 grams of fat.
How many kcal require to produce 1 ton of clinker?
760 kcal/ton clinker
If you wish to warm 100kg of water by 20C for your bath show that the amount of heat is 2000 kilocalories. Then show that this is equivalent to 8370 kJ?
To warm 100 kg of water by 20°C, you can use the formula ( Q = mc\Delta T ), where ( Q ) is the heat energy, ( m ) is the mass (100 kg), ( c ) is the specific heat capacity of water (1 kcal/kg°C), and ( \Delta T ) is the temperature change (20°C). Thus, ( Q = 100 , \text{kg} \times 1 , \text{kcal/kg°C} \times 20 , \text{°C} = 2000 , \text{kcal} ). To convert this to kilojoules, use the conversion factor ( 1 , \text{kcal} = 4.184 , \text{kJ} ), resulting in ( 2000 , \text{kcal} \times 4.184 , \text{kJ/kcal} = 8370 , \text{kJ} ).
How many kcal in 1g?
There are approximately 7.7 kcal in 1 gram of fat, 4 kcal in 1 gram of protein, and 4 kcal in 1 gram of carbohydrates. The exact number of kilocalories (kcal) in 1 gram depends on the specific macronutrient being measured. For alcohol, there are about 7 kcal per gram.
How do you convert WmK to KcalmhC?
To convert W/mK (watts per meter Kelvin) to kcal/mh°C (kilocalories per meter hour Celsius), you can use the following formula: 1 W/mK = 8.597 kcal/mh°C. Using the conversion factor, you can multiply the value in W/mK by 8.597 to obtain the equivalent value in kcal/mh°C.
How many kilocalories are there in 1 calorie?
1 kCal = 1000 Cal or I Cal = 1/1000 kCal
