The specific heat of aluminum is 897 J/kg K . This value is almost 2.3 times of the specific heat of copper. You can use this value to estimate the energy required to heat a 500 g of aluminum by 5 °C, i.e., Q = m x Cp x ΔT = 0.5 * 897* 5 = 2242.5 J.
How do I calculate specific heat?
Specific heat is the amount of heat required to raise one gram of any substance one degree Celsius or Kelvin. The formula for specific heat is the amount of heat absorbed or released = mass x specific heat x change in temperature.
How do you find the specific heat of aluminium?
The specific heat of aluminum is 897 J/kg K . This value is almost 2.3 times of the specific heat of copper. You can use this value to estimate the energy required to heat a 500 g of aluminum by 5 °C, i.e., Q = m x Cp x ΔT = 0.5 * 897* 5 = 2242.5 J.
How do you find the specific heat of a metal?
Use Q = sm∆T to determine the heat capacity of the metal. (Make sure to use the heat given off by the metal, the mass of the metal, and the temperature change of the metal in this calculation.)
What is the specific heat of aluminum?

How do you calculate aluminium?
Aluminum has an atomic weight of 26.9815 in Daltons or grams per mole (g/mol). This means if you have a certain number of moles of aluminum, you can multiply it by the atomic weight to figure out how many grams per mole of aluminum you have. This accounts for the weight of aluminum in its pure form.
What is the specific heat of kerosene?

How do you solve specific heat problems?
The specific heat capacity is the heat or energy required to change one unit mass of a substance of a constant volume by 1 °C. The formula is Cv = Q / (ΔT ⨉ m) .
What is Q in Q MC ∆ T?
Q = mc∆T. Q = heat energy (Joules, J) m = mass of a substance (kg) c = specific heat (units J/kg∙K) ∆ is a symbol meaning “the change in”
What is the specific heat of water?
One of water's most significant properties is that it takes a lot of energy to heat it. Precisely, water has to absorb 4,184 Joules of heat (1 calorie) for the temperature of one kilogram of water to increase 1°C. For comparison sake, it only takes 385 Joules of heat to raise 1 kilogram of copper 1°C.
What is the specific heat of a metal?
Specific heat is amount of energy, measured in either joules or calories, needed to raise the temperature of one gram of the substance one degree Celsius. Often applied to metallic elements, specific heat can be used as a basis for comparing energy absorption and transfer.
What is the specific heat of the unknown metal?
The specific heat capacity of the unknown metal is approximately 916 J kg − 1 K − 1 , which roughly corresponds to the heat capacity of aluminium as listed in the Handbook of Chemistry and Physics.
What metal has the highest specific heat?
| Substance Specific Heat (J/g°C) | Gold (s) 0.129 | Iron (s) 0.449 | Lead (s) 0.129 |
