0.902 J/gC is the specific heat of aluminum.
Use
(q)heat(Joules) = mass * specific heat * change in temperature
q = (480 g)(0.902 J/gC)(243 C - 23 C)
= 95261.2 Joules
------------------------------( call it 9.5 X 104 Joules )

The number of kilojoules needed to raise the temperature of 32.0 g of water from 12.0 degree centigrade to 54.0 degree centigrade is?
q(Joules) = mass * specific heat * change in temperature q = 32.0 grams H2O * 4.180 J/gC *(54.0 C - 12.0 C) = 5617.92 Joules this is, of course 5.62 kilojoules
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.
Aluminum melts at 934 Kelvins What is the equivalent temperature in degrees F?
1221.53 degree Fahrenheit
What is the final temperature of a 48.26 g sample of aluminum at 100 degree Celsius dripped into 34.47 g of water at 25.0 degree Celsius?
42.3 C
What is the melting point of medal?
It depends on the metal. For example, Iron (Fe) has a melting temperature above 2000 degrees F, while Aluminum (Al) has a melting temperature below 2000 degree F. Moreover, Lead (Pb) has a temperature considerably lower then both Iron and Aluminum.
How much heat is in fresh water?
It would depend on the temperature of the water, or average kinetic energy. (KE) However, what you may be looking for is how much heat is needed to raise the KE, or temperature, of water. 4.184 kilojoules per gram is the heat required to raise the temperature of water 1 degree Celsius.
How do you convert 2.35 kilojoules of heat to degree celsius?
To convert 2.35 kilojoules of heat to degrees Celsius, you need to know the specific heat capacity of the substance being heated. Once you have this value, you can use the formula: Heat energy (in joules) = mass * specific heat capacity * change in temperature. By rearranging the formula, you can calculate the change in temperature in degrees Celsius.
What is a sentence using the word degree?
The temperature was up by about one degree. The temperature rose about one degree. The temperature dropped about one degree.
What is the difference between temperature and degree?
A degree is a unit of temperature.
How are degree Celsius temperature related?
A degree Celsius is a measure of temperature.
How much energy is required to raise the temperature of one liter of water 1 degree centigrade?
The specific heat of water is 4.179 Joules per gram per degree Centigrade. The density of water is 1 gram per cubic centimeter, so one liter is 1000 grams. This means it takes 4179 Joules to raise one liter one degree Centigrade.
What is the temperature in degree C when the temperature is 59 degree F?
15 0C is the temperature for the required conversion.
