What is the C value for aluminum?
Specific heats and molar heat capacities for various substances at 20 C
Substance | c in J/gm K | Molar C J/mol K |
---|---|---|
Aluminum | 0.900 | 24.3 |
Bismuth | 0.123 | 25.7 |
Copper | 0.386 | 24.5 |
Brass | 0.380 | … |
Is specific heat capacity C or C?
The specific heat capacity c [J/(kg K)] of tissue describes how much energy is required to change the temperature of 1 kg of tissue by 1 K (=1°C). For example, the lower specific heat capacity of fat compared to other soft tissue indicates, that fat requires less energy to obtain a certain temperature increase.
What is the heat capacity of 10kg aluminum?
A 10-kg piece of aluminum (which has a specific heat of 900 J/kg⋅°C) is warmed so that its temperature increases by 5.0 C°.
How do you find the specific heat of aluminum?
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.

Does aluminum have a high specific heat?
Thus, the aluminum must require more energy to change its temperature. Therefore, aluminum has the higher specific heat.
What is C in specific heat capacity?
In SI units, specific heat capacity (symbol: c) is the amount of heat in joules required to raise 1 gram of a substance 1 Kelvin. It may also be expressed as J/kg·K. Specific heat capacity may be reported in the units of calories per gram degree Celsius, too.
What does 4.184 J GC represent?
The units of specific heat in the SI system are J/g-K. Because there are 4.184 joules in a calorie, the specific heat of water is 4.184 J/g-K.
