How many joules of energy are required to raise the temperature of 20g of aluminum from 10 degrees C to 15 degrees C?
Heat energy Q = mass x specific heat capacity x temperature change.
Q = m*c*delta T
Q = Joules
m = kg
c (aluminum) = 895.8 J/kg
delta T = degr.C temp. change
Answer: Q = (20/1000) x 895.8 x 5 = 89.58 Joules
(Specific heat capacity of aluminum is obtained by multiplying its specific heat of 0.214 with c of water which is 4186 J/kg = 0.214 x 4186 = 895.8 J/kg).

How much energy is needed to raise the maximum temperature of 10kg of water from 20 degrees Celsius to 80 degrees Celsius?
The energy required to raise the temperature 1 degree Celsius of 1 gram of water (1 mL) is 1 calorie (=4.18 J). So for 1 kg, 1Kcal (= 4180 J = 4.18 KJ) is required. To raise it 60 degrees, just multiply by 60 and for 10 kg multiply by 10 again. That would make 2.508 MJ (= 2508000 J) Now this is not completely accurate. The energy required to raise the temperature of water differs at 20 degrees from that at 60 degrees. The difference is small (~0.05 J or something like that) but still present.
What is the BTU required to raise the temperature of 10 pounds of water from 50 degrees to 70 degrees?
200 BTU. I'm assuming your temperatures are in Fahrenheit, since all of your other measurements are in the Imperial system. A BTU is defined as the amount of energy required to raise the temperature of 1 pound water by 1 degree F, so the temperature is raised by 20 degrees, and 10 pounds of water: 20 x 10 = 200
How much energy is required to raise 160 cfm of air from 10 to 170 degrees f?
The amount of energy that is required to 160 cfm of air from 10 to 170 degrees F is 200 btu. T he formula is weight x specific heat x temperature difference so we have10 pounds x 1.00 x 2010 for 10 pounds of water.
Is temp or heat measured in degrees?
If you want to be pedantic, scientists measure temperature in kelvins, not degrees. Heat is energy and is measured in energy units, like joules.
How many BTU to reach 900 deg C?
To determine the amount of BTU (British Thermal Units) required to reach a temperature of 900 degrees Celsius, you need to know the mass of the substance being heated and its specific heat capacity. The formula to calculate the BTUs required is: BTU = mass (lbs) × specific heat (BTU/lb°F) × temperature change (°F). Since 900 degrees Celsius is equivalent to 1652 degrees Fahrenheit, the energy required will vary based on the material you are heating. For an accurate calculation, specific details about the material's mass and specific heat capacity are needed.
How much energy is required to raise the temperature of 0.2kg of aluminum for 15 degrees celsius to 18 degrees celsius?
The specific heat capacity of aluminum is 0.9 J/g°C. To calculate the energy required to raise the temperature of 0.2kg of aluminum by 3 degrees Celsius, you would use the formula: Energy = mass x specific heat capacity x temperature change. Substituting the values into the formula, Energy = 0.2kg x 0.9 J/g°C x 3°C = 0.54 Joules.
How much energy is required to raise the temperature of 0.2 kg of aluminum from 15 degrees celsius to 18 degrees celsius?
The specific heat capacity of aluminum is 900 J/kg°C. The change in temperature is 3°C. Using the formula Q = mcΔT, the energy required would be 0.2 kg * 900 J/kg°C * 3°C = 540 J. So, the energy required to raise the temperature is 540 Joules.
Which would take more energy to increase temperature by 5 degrees water or Aluminum?
It would take more energy to increase the temperature of water by 5 degrees than aluminum. This is because water has a higher specific heat capacity, meaning it requires more energy to raise its temperature compared to aluminum.
How much energy is required to raise the temperature of 3kg of aluminum from 18 degrees Celsius to 23 degrees Celsius?
The specific heat capacity of aluminum is 0.902 J/g°C. First, convert 3kg to grams (3000g). Then, calculate the change in temperature (23°C - 18°C = 5°C). Finally, use the formula Q = mcΔT to find the energy required: Q = 3000g * 0.902 J/g°C * 5°C.
Is a green heating system unable to go beyond 68 degrees?
If you are asking why a green heating system will not go above 68 degrees Fahrenheit then one reason is to save energy. The higher the temperature the more energy required to get to that temperature and the more energy required to keep that temperature.
How many joules would be required to heat 0.5kg of aluminum?
The specific heat capacity of aluminum is 0.897 J/g°C. To calculate the energy required to heat 0.5kg of aluminum by a certain temperature change, you would use the formula: Energy = mass x specific heat capacity x temperature change If you have the temperature change, you can plug the values into the formula to find the total energy in joules.
How much energy is required to raise the temperature of 3 kg of aluminum from 18 degrees C to 23 degrees C?
The specific heat capacity of aluminum is 0.897 J/g°C. First we need to convert the mass to grams: 3 kg = 3000 g. Then we can use the formula: energy = mass x specific heat x change in temperature. Plugging in the values: energy = 3000 g x 0.897 J/g°C x (23°C - 18°C) = 13,485 J. So, 13,485 Joules of energy is required.
How much heat energy is needed to raise the temperature of a 055kg sample of aluminum from 22.4 degrees celsius to 94.6 degrees celsius?
The heat energy required can be calculated using the formula: Q = mcΔT, where Q is the heat energy, m is the mass of the aluminum (0.055 kg), c is the specific heat capacity of aluminum (900 J/kg°C), and ΔT is the change in temperature (94.6°C - 22.4°C = 72.2°C). Plugging in the values, we get Q = 0.055 kg * 900 J/kg°C * 72.2°C = 3582.7 J. Hence, 3582.7 Joules of heat energy is needed to raise the temperature of the aluminum sample.
How much energy is required to raise 3 kg of aluminum from 18 degrees C to 23 degrees C?
The energy required to raise the temperature of a substance can be calculated using the specific heat capacity formula: Q = mcΔT, where Q is the energy transferred, m is the mass of the substance, c is the specific heat capacity, and ΔT is the change in temperature. For aluminum, the specific heat capacity is 0.897 J/g°C. Converting the mass to grams (3000 g), the energy required would be: Q = 3000 g * 0.897 J/g°C * 5°C = 13,455 J.
How much energy is required to raise the temperature of 0.2 kg of aluminum from 15 degrees C to 18 degrees C?
The specific heat capacity of aluminum is 0.902 J/g°C. First we convert the mass from kg to grams (0.2 kg = 200 g). Then we calculate the energy using the formula: Q = mcΔT, where Q is the energy, m is the mass, c is the specific heat capacity, and ΔT is the change in temperature. Plugging in the values, we get Q = 200g * 0.902 J/g°C * (18 - 15)°C. Solving this gives us the energy required to be approximately 541 J.
How many kilowatts are required to raise the temperature of 1000 liters of water by 10 degrees centigrade?
Kilowatts is a unit of energy rate, while the temperature required to raise a specific volume of water by a specific amount of degrees is a unit of energy, not energy rate. The question cannot, therefore, be answered as stated. Please restate the question.
