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
Aluminum melts at 934 Kelvins What is the equivalent temperature in degrees F?
1221.53 degree Fahrenheit
Does aluminum need more or less energy than lead to raise its temperature one degree?
more
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.
What is The thermal energy of a solid?
The thermal energy of a solid or a volume of liquid is the specific heat of a material multiplied by the object's mass and temperature (absolute). I.E. 1 kg of water at 27 degrees C: specific heat of water is 4.186 Kilojoules per kilogram-degree Celsius. Multiply that by the mass and the absolute temperature (Degrees Kelvin, or 273.15 + degrees Celsius) to get the thermal energy in kilojoules
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.
The difference of the heat from temperature?
Temperatue- It is the degree of hotness or coldness of an object. Heat - Heat is a form of energy that can be transferred from one object to another object.
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 are degree Celsius and temperature related?
A degree Celsius is a measure of temperature.
