How much heat do you need to raise the temperature of 100 g of aluminum from 30 to 150 degrees?
To calculate the heat required to raise the temperature of aluminum, you can use the formula ( Q = mc\Delta T ), where ( Q ) is the heat energy, ( m ) is the mass (100 g), ( c ) is the specific heat capacity of aluminum (approximately 0.897 J/g°C), and ( \Delta T ) is the change in temperature (150°C - 30°C = 120°C). Plugging in the values:
[ Q = 100 , \text{g} \times 0.897 , \text{J/g°C} \times 120 , \text{°C} \approx 10764 , \text{J}. ]
Thus, you need about 10,764 Joules of heat.

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 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 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.
Which would have higher temperature change water or aluminum?
Starting from the same temperature and for the same amount of heat input, aluminum would wind up with a higher temperature than water because water has a higher heat capacity (it takes more energy to raise its temperature) than aluminum.
Does aluminum need more or less energy than lead to raise its temperature one degree?
Aluminum needs less energy than lead to raise its temperature by one degree, as aluminum has a lower specific heat capacity compared to lead. This means that aluminum can absorb and release heat more easily than lead for the same change in temperature.
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 much heat must be added to 50 grams of aluminum at 25c to raise temperature to 135c?
The specific heat capacity of aluminum is 0.897 J/g°C. By using the formula Q = mcΔT, where Q is the heat energy, m is the mass, c is the specific heat capacity, and ΔT is the change in temperature, you can calculate that 5,381.25 Joules of heat energy must be added to raise the temperature of the aluminum from 25°C to 135°C.
How many joules does it take to raise temperature from 30 degrees Celsius to 45 degrees Celsius?
To raise the temperature of a substance, you need to calculate the heat energy using the specific heat capacity of the substance. Without knowing the specific heat capacity of the substance in question, it's not possible to determine the exact amount of energy required to raise the temperature from 30 to 45 degrees Celsius.
Will aluminum heat up in the sun?
Yes, aluminum will heat up in the sun as it absorbs and retains heat well. Its thermal conductivity allows it to quickly raise in temperature when exposed to sunlight.
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 of these substances requires the least amount of energy to raise its temperature 'wood' 'water' 'gold' or 'aluminum'?
Aluminum requires the least amount of energy to raise its temperature compared to wood, water, and gold. This is because aluminum has a lower specific heat capacity, meaning it can heat up more quickly with less energy input.
What is the measure of how much heat will raise the temperature of 1 kg of a substance by 1 degrees c?
The specific heat of the substance.
